A student has a 10.0g sample of CaBr2 . Show the setup of the calculation to determine the number of moles of CaBr2 in the sample. Include units in the setup.

The moles of CaBr2 in the given sample is  0.30127 moles

Explanation:

Given,

CaBr2  Gram=10

we have,

Molar mass of CaBr2 = 199.886 g/mol

1 mole= 6.022×10^23

Mole= 10.00 g*6.022×10^23 /199.886 g/mol

Mole=0.30127 moles

The moles of CaBr2 in the given sample is  0.30127 moles
