Convert 18.82 L NO gas (At STP) to grams:

(Answer) grams (4 SF)

Explanation:

Hello!

In this case, since the STP conditions are known as 273.15 K of temperature and 1.00 atm of pressure, we can use the ideal gas equation to compute the moles of NO gas first:

Next, since the molar mass of NO is 30.01 g/mol the resulting mass in grams is:

Which has four significant figures.

Best regards!

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
