How many grams of KBrO2 are there in 0.168 moles

Mnenie [13.5K]

Hey There!

Molar mass KBrO2 = 151.0011 g/mol

1 mole KBr --------- 151.0011 g

So in 0.168 moles :

jekas [21]

Answer:

Time = 3.27s

Explanation:

Time = Distance / Speed

Time = 42.2 / 12.9 = 3.2713

When you multiply the number of significant figures in the result is the same as the number with the least significant figures.

In this case 42.2 has 3 significant figures and 12.9 also has 3 significant figures, therefore the answer must have 3 significant figures too.

Time = 3.27 s
