For the reaction shown, calculate how many moles of no2 form when each of the following completely reacts. 2n2o5(g)→4no2(g)+o2(g) part a 1.0 mol n2o5 express your answer using two significant figures. nothing mol m o l request answer part b 5.4 mol n2o5 express your answer using two significant figures.

For part A: The number of moles of is 2.0 moles.

For part B: The number of moles of is moles.

Explanation:

For the given chemical equation:

By Stoichiometry of the reaction:

2 moles of produces 4 moles of

So, 1.0 moles of will produce = of

Hence, the number of moles of expressed in two significant figures are 2.0 moles.

By Stoichiometry of the reaction:

2 moles of produces 4 moles of

So, 5.4 moles of will produce = of

To express it in two significant figures, we round this value of 10.8 mol to 11 mole and then express it in scientific notation.

Scientific notation is defined as the way of representing a number which have very large value or very small value and is written in the decimal form.

Hence, the number of moles of expressed in two significant figures are moles.
