Question

Calculate the number of CO2 molecules in 0.88 g of CO2​

Answer 1

Answer:

Step-by-step explanation:

88 g co2 is 2 moles of co2 ( 1 mole co2 = 44 gm) . Since 1 mole co2 has 2 moles of O atom 2 moles ie 88 gm will have 4 moles which is 4 times avogardos no of atom ie 4* 6.023 *10^23.

Answer 2

Answer:

0.02moles

Step-by-step explanation:

given mass of CO²=0.88g

molar mass of CO²= 12+2(16)

                               = 12+32

                               =44g

no. of CO² molecules= given mass/molar mass

                                   =0.88/44

                                    = 0.02moles
