Formaldehyde's molecular formula is CH2O, and according to the atomic masses of its constituent elements, the gas has a molar mass of 30g/mol. If you have 12.3g of it, then set up a direct proportion where 30/1=12.3/x. Solve for x to get 0.41 moles. Multiply this by the constant of 22.4 liters/mole of any gas at STP, and you get 22.4x0.41=9.184 liters CH2O at STP.
The volume of a gas at STP (standard temperature and pressure) is 22.4 L per mole. To find the volume of formaldehyde gas, we need to convert grams to moles using the molar mass of formaldehyde (30.03 g/mol). Then, we can use the ideal gas law to calculate the volume.

At STP 32 grams of O2 would occupy the same volume as?
At STP (standard temperature and pressure), 32 grams of O2 would occupy the same volume as 22.4 liters, which is the molar volume of any ideal gas at STP.
What volume will be occupied by 132 grams of propane at stp?
At STP (standard temperature and pressure: 0 degrees Celsius and 1 atm), the volume taken up by 132 grams of propane can be calculated using the ideal gas law. First, find the number of moles of propane using its molar mass, and then use the ideal gas law equation to calculate the volume, which will be around 66.6 L.
How many grams of carbon dioxide will occupy a volume 500.0 ml at STP?
At standard temperature and pressure (STP), 1 mole of any gas occupies 22.4 liters. To convert 500.0 ml to liters, you divide by 1000 (since 1 liter = 1000 ml). Then, use the ideal gas law equation (PV = nRT) to find the number of moles of carbon dioxide, and finally convert moles to grams using the molar mass of CO2.

Calculate the density of nitrogen gas, in grams per liter, at STP?
At Standard Temperature and Pressure (STP), which is defined as 0 degrees Celsius (273.15 Kelvin) and 1 atmosphere pressure, the molar volume of an ideal gas is approximately 22.4 liters/mol. The molar mass of nitrogen gas (Nā) is approximately 28.02 grams/mol. To calculate the density (D) of nitrogen gas at STP, you can use the ideal gas law: ļæ½ = Molar mass Molar volume at STP D= Molar volume at STP Molar mass ā ļæ½ = 28.02 ā g/mol 22.4 ā L/mol D= 22.4L/mol 28.02g/mol ā ļæ½ ā 1.25 ā g/L Dā1.25g/L Therefore, the density of nitrogen gas at STP is approximately 1.25 grams per liter.
What is the element that at stp weighs 7.49 gm and has a volume of 1.65 cubic centimeters?
The element is lithium (Li). It has a density of 4.54 g/cm3 and at STP (standard temperature and pressure), a volume of 1.65 cm3 would weigh approximately 7.49 grams.
How many grams of carbon dioxide will occupy a volume 500.0 ml at STP?
At standard temperature and pressure (STP), 1 mole of any gas occupies 22.4 liters. To convert 500.0 ml to liters, you divide by 1000 (since 1 liter = 1000 ml).

What volume is occupied by 55 g of methane CH4 (g) at STP?
To calculate the volume occupied by 55 g of methane (CH4) at STP (Standard Temperature and Pressure), we first need to determine the number of moles of methane. The molar mass of methane is 16 g/mol. Therefore, 55 g of methane is equal to 55 g / 16 g/mol ā 3.44 mol. At STP, 1 mol of any gas occupies approximately 22.4 L. Therefore, 3.44 mol of methane would occupy approximately 3.44 mol x 22.4 L/mol ā 77.1 L.
