Express your answers using two significant figures separated by commas. 3.3 1.55 |- Mol C, Mol SiC, Mol CO = Submit tty Answers Give Up Part E Complite the fifth row. Express your answers using three significant figures separated by commas

Explanation / Answer

1st row is:

1, 3, 1, 2

2nd row is multiplying 1st row by 3 because mol of C is tripled

So, 2nd row is:

3, 9, 3, 6

3rd row is multiplying 1st row by 8 because mol of CO becomes 8 times

So, 3rd row is:

8, 24, 8, 16

4th row is multiplying 1st row by 3.3 because mol of SiO2 becomes 3.3 times

So, 3rd row is:

3.3, 9.9, 3.3, 6.6

Answer C:

8, 24, 8

Answer D:

9.9, 3.3, 6.6
