A0.420 m ca(oh)2 solution was prepared by dissolving 64.0 grams of ca(oh)2 in enough water. what is the total volume of the solution formed? 1.07 liters 1.23 liters 2.05 liters 2.18 liters

2.05 liters

Calculate the molar mass of Ca(OH)2 =74.09g/mol

Calculate how many mol of Ca(OH) are in 64g

n=m/MM
n=64/74.09
n=0.86 mol

Calculate the volume of solution
M=n/V => V=n/M

V= 0.86 mol/ 0.420M
V= 2.05 liters

Ithe undersigned only for use your own email and delete any and copies and of the itself and to be there is a good timewhat does a decrease in temperature indicate about the molecules in a sample of liquid water? decreased chemical energy of the moleculesdecreased kinetic energy of the moleculesincreased chemical energy of the moleculesincreased kinetic energy of the moleculeshow does a sample of helium at 15 â°c compare to a sample of helium at 215 k? the helium at 15 â°c has a higher average kinetic energy than the sample at 215 k.the helium at 15 â°c has lower nuclear energy than the sample at 215 k.the helium at 15 â°c has slower-moving atoms than the sample at 215 k.the helium at 15 â°c has smaller atoms than the sample at 215 k.
