Question

Convert 7.41 x 1024 molecules of C2H2 to grams

Answer 1

To convert molecules of C2H2 to grams, we need to use the molar mass of C2H2, which is 26.04 g/mol.

First, we need to calculate the number of moles in 7.41 x 10^24 molecules of C2H2:

7.41 x 10^24 molecules / 6.022 x 10^23 molecules/mol = 12.31 mol

Then, we can use the formula:

mass = moles x molar mass

mass = 12.31 mol x 26.04 g/mol = 320.4624 g

Therefore, 7.41 x 10^24 molecules of C2H2 is equivalent to 320.4624 grams.
