What is the percent mass of calcium chloride (cacl2)? show the steps.

The total molar mass of CaCl2 is (1 × 40.078 grams/mole) + (2 × 35.45 grams/mole) = 110.978 grams/mole. Notice that the molar mass of calcium in the compound is 40.078 grams/mole.

= 0.3611

0.3611 × 100% = 36.11%

Rounded to the nearest percent, the final answer is 36%.

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
