Let's start with the Ideal Gas Law formula. PV nRT where P pressure V volume n number of moles of gas R gas constant (0.0821 L&183;atmmol&183;K) T absolute temperature If we solve the equation for volume, we get V (nRT)P We know everything we need to find the volume now except the number of moles of gas.
How many moles are there in 65 g of NaOH Question 2 Calculate the volume that 8 g of oxygen gas occupies at standard temperature and pressure. Question 3 What is the mass of 56 dm3 of nitrogen gas at standard temperature and pressure Question 4 45 g of NaOH is dissolved in water and made up to a volume of 250 cm3. Calculate the. VIDEO ANSWER we begin this question by calculating the number off molds off water in one leader. The number off molds can be calculated as follows.
