To find the volume of a gas, we can use the ideal gas law: PV = nRT. First, calculate the moles of nitrogen using the given mass and molar mass. Then, rearrange the ideal gas law to solve for volume: V = nRT/P. Plug in the values for n (moles), R (ideal gas constant), T (temperature in Kelvin), and P (pressure) to find the volume.

What is the significant figures for 56g?
The significant figures for 56g are two, as there are two non-zero digits in the number.
What mass of oxygen contians the same number of molecules as 42g of nitrogen?
To find the mass of oxygen containing the same number of molecules as 42g of nitrogen, we need to compare their molar masses. The molar mass of nitrogen is 28 g/mol and oxygen is 32 g/mol. Since the same number of molecules of each substance have the same number of atoms, we can calculate the mass of oxygen by setting up a proportion: (42g N) / (28 g/mol N) = (x g O) / (32 g/mol O) Solving for x, the mass of oxygen containing the same number of molecules as 42g of nitrogen is 56g.
How many grams of lead nitrate will dissolve in 100mL of cold water?
Approximately 161 grams of lead nitrate will dissolve in 100mL of cold water at room temperature.
How many moles of iron atoms are there in 56g of iron?
The amount of particles (any kind) in ONE mole (of any substance) is always equal to Avogadro's number: 6.02*10+23 (This is the definition of a 'Mole'. It is just a number like a 'dozen' -12- or 'gross' -144-, though much larger. There is nothing 'chemical' in this number, however) So, here is your answer: 0.56 mole = 0.56 * 6.02*10+23 = 3.37*10+23
How do you prepare 1 ltr koh 0.05N?
To prepare 1 liter of 0.05N KOH solution, you would need to dissolve 2.8 grams of potassium hydroxide (KOH) in water and dilute to a final volume of 1 liter. Always remember to wear appropriate safety gear and handle chemicals with caution.
What does 56g equals?
56g=0.56kg
What is the density of an object with a mass of 56g and 90 ml?
Density = Mass/Volume = 0.622... grams per ml
What is the density of a ball that has a mass of 56 g and a volume of 28 cm?
Assuming the volume is in cubic cm and not cm(!), Density = Mass/Volume = 56g/28cm3 = 2 grams per cm3
What is 130 percent of 56g?
130% of 56g = 130% * 56 = 1.3 * 56 = 72.8g
What is the volume of an object with a mass of 25 point 8g and also has a density of 2 point 56g?
Density = Mass/Volume => V = M/D So Vol = 25.8/2.56 = 10.1 units (approx) of the volume in which the density was expressed.
What is the significant figures for 56g?
The significant figures for 56g are two, as there are two non-zero digits in the number.
How much energy is required to melt 56g?
The energy required to melt a substance can be calculated using the formula: Energy = mass x heat of fusion. For water, the heat of fusion is 334 J/g. Therefore, the energy required to melt 56g of water would be 56g x 334 J/g = 18,704 J.
