yes, thats quite correct

5000 mg / 250 mg/mL = 20 mL\n\n20 mL - 8.6 mL = 11.4 mL

The density can be assumed to be 1.0 g/ml.  \n\nSo you have 25 ml x 1.0 g/ml = 25 g H2O\n\nThe molar mass of water is 18 g/mol, so you have:\n\n25 g H2O/18 g H2O/mol H2O = 1.4 mol H2O

Just remember M1*V1=M2*V2 where M is molarity and V is volume. A little Algebraic manipulation gives you:\n\nV1 = (M2*V2)/M1\n     = (0.195*15.5)/18.0\n     = 0.168 L = 168 mL

a = (v_f - v_i)/t\n-0.25g = (0-v)/t\n0.25g = v/t\nt = 4v/g\n\nd = v*t + 0.5*a*t^2\nd = v*4v/g + 0.5*(-0.25g)*(4v/g)^2\nd = (4v^2)/g - 0.125 *g* (16 v^2 )/g^2\nd = (4v^2)/g - (2v^2)/g\n\nd = (2*v^2)/g

F*m = μ*Joules→ m = .25*40000000/1000 = 10000m = 10 km

F = KM1M2/r^2\n\nwhere K is the constant, M1 and M2 are the magnetic moments, and r is the distance between them.

too little\n\n0.25 liters = 250 milliliters\n\nyou need to add 50 milliliters more\n\nwhich 50 milliliters = 0.05 liters

$3.60 x 0.75 = $2.70\n\n(2m = 2000mm) + (34cm = 340mm) + 8mm = 2348mm\n\n36/6 = 6 x 4 = $24\n\n0.8km + 0.09km + 3km = 3.89km\n\n6 x .25 = 1.5L = 1500ml

The question is a little faulty but I think I know what you meant.\n\nIf d is 30.5, then r is half that, 15.25.  You mean pi which is about 3.14.\n\nIf I use that value of pi, and r is 15.25, then area is pi r squared, or 3.14 x 15.25 x 15.25 which is 730.24625.\n\nUsing a better value of pi, I got 730.61664.

the answer that i got is 3.10 M. \n\n3.25 g NaOH/40.00 g NaOH = .0813 mol NaOH\n\n26.2 mL / 1000mL = .0262 L\n\nM= .0813 mol / .0262 L = 3.10 M

Volume = L*W*H\nV = (15cm)(35cm)(H)\n(5.4g)/(2.7g/cm^3)=525cm^2*H\n2cm^3 = 525cm^2*H\n\nThickness or height = (2/525)cm\nT = 0.0038095238095238... the 380952 repeats
