It takes 0.16 g of helium (he) to fill a balloon. how many grams of nitrogen (n2) would be required to fill the balloon to the same pressure, volume, and temperature?

The mass of nitrogen gas required to fill the balloon is 1.12 grams.

Explanation:

We are given:

Mass of helium gas = 0.16 g

We need to calculate the mass of nitrogen gas that can fill the balloon at same pressure, volume and temperature. This means that the moles of both the gases filling up balloon will be same.

So, to calculate the number of moles, we use the equation:

Given mass of Helium = 0.16 g

Molar mass of helium = 4.00 g/mol

Putting values in above equation, we get:

Now, calculating the mass of nitrogen gas using same above equation, we get:

Moles of nitrogen gas = 0.04 moles

Molar mass of nitrogen gas = 28.01 g/mol

Putting values in above equation, we get:

Hence, the mass of nitrogen gas required to fill the balloon is 1.12 grams.

colorectal cancer may also develop from areas of abnormal cells in the lining of the colon or rectum. this area of abnormal cells is called dysplasia and is more commonly seen in people with certain inflammatory diseases of the bowel such as crohn's disease or ulcerative colitis.

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6
