Question

Find the mass of 1.5 mole of co2 molecule?​

Answer 1

Answer:

The general formula relating moles (n), mass in grams (m), and molar mass in g/mol (M) is:

n = m/M

It can be rearranged to calculate mass when you have moles and molar mass.

m = n × M

First calculate the molar mass (M) of CO2.

M C=12 g/mol, M O=16 g/mol

M CO2 = 12 g/mol + 2(16 g/mol) = 44 g/mol

To calculate the mass of a given number of moles of a substance, multiply given moles by the molar mass of the substance. (m = n × M)

1.5 mol CO2 = (44 g CO2/1 mol CO2) = 66 g CO2

Answer: There are 66 g CO2 in 1.5 mol of CO2
