Question

You have 88 grams of CO2. How many particles are present? a 1.2 b 1.2 x 10^24 c 2 d 2 x 10^24

Answer 1

In order to find the number of particles of 88 grams of CO2, we need to find the number of moles, using its molar mass, 44g/mol:

44g = 1 mol

88g = x moles

x = 2 moles of CO2 in 88 grams

Now that we have the number of moles, we can find the number of particles, using the Avogadros constant umber, whic h is 6.02*10^23 atoms or particlesfor each mol:

6.02*10^23 particles = 1 mol

x particles = 2 moles

x = 1.2*10^24 particles in 88 grams of CO2, letter B
