What is the mass of 9.30 moles of SiH4 in grams?

Answer 1

first you set up your ratio;

9.3moles

1mole = 32g

9.3 is the number of moles you're trying to find

32 comes from adding the mass numbers of both elements;

Si=28g

H=1g, but there's four, so you multiply it by 4, hence the 32

now you crossmultiply; so multiply 9.3 by 32

you get 297.6, then divide by 1 so 9.3 moles SiH4 is 297.6g. follow the same pattern every time and you'll be fine; hope this helps

Answer 2

The molar mass of SiH4 is approximately 32.117 grams per mole. So, 9.30 moles of SiH4 has a mass of 298.69 grams.

Answer 3

The molar mass of SiH4 is approximately 32.1 g/mol. To find the mass of 9.30 moles of SiH4, you would multiply the number of moles by the molar mass: 9.30 moles × 32.1 g/mol = 298.53 grams.
