Calculate the volume of a balloon that can hold 113.4 g of nitrogen dioxide, NO2 gas at STP-

55.18 L

Explanation:

First we convert 113.4 g of NO₂ into moles, using its molar mass:

Then we use the PV=nRT formula, where:

Input the data:

And solve for V:

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
