To calculate, divide the amount obtained by the amount which entered the operation, times 100 to express in percent. The molecular weight doesn't change, so units of grams may be used.

To find the theoretical yield, you must know the equation for the reaction and how many moles of each reactant you are starting with. Balance the chemical equation. For example, take the equation H + O = H2O. To balance this you need two hydrogen on the left to balance the two hydrogen in water, so 2H + O = H2O.

Divide the amount of Btus per hour by 1,000 to calculate the amount of MBH. For example, the amount of Btus per hour is 20,000. Dividing that by 1,000 would result in 20 MBH.

Most scientific papers have stated the formula for extraction yield calculation like this, The yield of extract (extractable components) expressed on dry weight basis of pulp was calculated from the following equation: Yield (g/100 g) = (W1 × 100)/W2 where W1 is the weight of the extract residue obtained after solvent ...

Here's how to calculate gross rental yield: Sum up your total annual rent that you would charge a tenant. Divide your annual rent by the value of the property. Multiply that figure by 100 to get the percentage of your gross rental yield.

The simplest way to calculate a bond yield is to divide its coupon payment by the face value of the bond. This is called the coupon rate. If a bond has a face value of $1,000 and made interest or coupon payments of $100 per year, then its coupon rate is 10% ($100 / $1,000 = 10%).

If you perform the experiment, you'll end up with a smaller amount, the actual yield. To express the efficiency of a reaction, you can calculate the percent yield using this formula: %yield = (actual yield/theoretical yield) x 100.

Simply stated, a stock's dividend yield is calculated by taking its dividend-per-share and then dividing it by its price-per-share. The result is then expressed in percentage terms.

Percent yield is the weight of copper which you obtained, divided by the total weight of copper you started with in the form of copper nitrate, multiplied by 100%. A good experiment will give you a high % recovery of a pure product. Complete Table 4 by writing a balanced equation for each reaction.

The formula is EP weight ÷ AP weight × 100 = yield %. Yield percentage is important because it tells you several things: how much usable product you will have after processing; how much raw product to actually order; and the actual cost of the product per dollar spent.

The calculation for distribution yields employs the most recent distribution, which may be interest, a special dividend, or a capital gain, and multiplies the payment by 12 to get an annualized total. The annualized total is then divided by the net asset value (NAV) to determine the distribution yield.

If your generator capacity is 10 megawatts, it can produce 10 megawatts each hour, or 10 MWh. Multiply the MWh figure from Step 1 by 8,760, the number of hours in a year. In this example, that would yield 87,600 MWh total annual power production. Divide the annual MWh figure from Step 2 by 1,000 to get GWh.

Divide the number of grams of product obtained experimentally, by the number of grams obtained in the theoretical yield calculations and multiply by 100 to calculate the percent yield. Example: Assume 2.96g of salicylic acid was obtained experimentally.

You must divide the grams of your actual yield by the grams of the theoretical yield and multiply by 100 in order to obtain percent yield.
