Question

calculate the number of moles in each of the following 10.0g of caco3 and 1×1023 molecules of co2 ​

Answer 1

Answer:

0.1 moles of CaCo3 and 0.166 moles of CO2,please mark this the brainliest!

Explanation:

1.)

since 1 mole of CaCO3 has the molar mass of 100 g

10g are equivalent to 10/100=0.1 moles of CaCO3

2.)

1 mole of CO2 will contain 6.022 *10²³  molecules

hence (im assuming you have written 1*10²³) molecules will be equal to

10²³/(6.022 *10²³)=0.166 moles

I hope this answer helps you!
