what is the molar mass of calcium chloride dihydrate (cacl2⋅ 2h2o) ?

be sure to include the mass of all elements in the formula including the elements in water.

64 g/mol

111 g/mol

147 g/mol

258 g/mol

Explanation:

The atomic weights of the elements:

Ca=40.078 g/mol

Cl=35.453 g/mol

H=1.008 g/mol

O=15.999 g/mol

The calcium chloride dihydrate:

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
