Chandra wants to know how many moles are contained in 150.0 g ccl4 (carbon tetrachloride). what quantity of ccl4 should she use to make this conversion?
a. number of moles
b. molecular mass
c. molar mass
d. mole ratio

c.  molar mass

Explanation:

Moles is denoted by given mass divided by the molecular mass ,

Hence ,

n = w / m

n = moles ,

w = given mass ,

m =   molar mass.

From the question ,

given mass of CCl₄=  w = 150.0g .

and ,

since ,

The molar mass of CCl₄ = m =  153.82 g / mol

By using the above equation ,

moles can be calculated as -

n = w / m

n = 150.0g /  153.82 g / mol = 0.975 mol.

c.  molar mass

Explanation:

Moles is denoted by given mass divided by the molecular mass ,

Hence ,n = w / m

n = moles ,

w = given mass ,

m =   molar mass.

From the question , given mass of CCl₄=  w = 150.0g .

and ,since ,The molar mass of CCl₄ = m =  153.82 g / mol

By using the above equation ,

moles can be calculated as -

n = w / m

n = 150.0g /  153.82 g / mol = 0.975 mol.
