How many moles of water are contained in 1.99x10^26 molecules of water?

330 moles

Explanation:

I mole of water = 6.022 × 10²³ molecules

I molecule = 1 ➗ 6.022 × 10²³ moles

1.99×10‘’ 26 molecules  = (1.99×10‘’ 26) ÷6.022 × 10²³ moles

Number of moles = 1.99/6.022 × 10" 26-23

Number of moles = 0.33 × 10³

Number of moles = 330 moles
