How many moles are present in 0.12g of helium?
To calculate the number of moles in 0.12g of helium, you need to use the molar mass of helium. The molar mass of helium is approximately 4g/mol. Therefore, 0.12g of helium is equivalent to 0.12g / 4g/mol = 0.03 moles of helium.
What is the mass in grams of 1.5 moles of helium?
The mass of 1,5 moles of helium is 6,003 903 g.
How many moles are in 27.4 g of water?
27.4 g H2O x 1 mole/18 g = 1.52 moles
what is the volume occupied by 15 g of helium?
The volume occupied by 15 g of helium can be calculated using the ideal gas law equation. First, convert grams to moles using the molar mass of helium. Then, apply the ideal gas law equation, V = nRT/P, where n is the number of moles, R is the ideal gas constant, T is the temperature, and P is the pressure.
How many moles are in 4.5 g of AgNO3?
To find the number of moles in 4.5 g of AgNO3, you first need to determine the molar mass of AgNO3 which is 169.87 g/mol. Then you can use the formula: moles = mass / molar mass. Therefore, moles = 4.5 g / 169.87 g/mol ≈ 0.0265 moles.
How many grams are in 0.775 moles of helium?
The mass of helium equivalent to 0,775 moles is 3,102 g.
How many moles are present in 40g of helium?
4 g of helium is equivalent to 1 mole of helium
How many moles are present in 205 g of helium?
To find the number of moles present in 205 g of helium, we need to use the molar mass of helium, which is approximately 4 g/mol. Divide the given mass by the molar mass to get the number of moles. In this case, 205 g / 4 g/mol = 51.25 moles of helium.
How many moles are there in 0.12g of helium?
4 g or helium is 1 mole. So, 0.12 g of helium is 0.03 mole
How many moles does g of helium he contain?
To calculate the number of moles of helium in a given mass (g), you can use the formula: [ \text{moles} = \frac{\text{mass (g)}}{\text{molar mass (g/mol)}} ] The molar mass of helium is approximately 4.00 g/mol. So, if you have a specific mass of helium, divide that value by 4.00 g/mol to find the number of moles.
How many moles are present in 205g of helium?
To calculate the number of moles, you need to divide the given mass by the molar mass of helium. The molar mass of helium is approximately 4 g/mol. Therefore, the number of moles in 205g of helium would be 205g / 4g/mol = 51.25 mol.
A helium balloon contains 0.46 g of helium how many moles of helium does it contain?
To find the number of moles of helium in the balloon, you need to divide the mass of helium by its molar mass. The molar mass of helium is approximately 4 g/mol. Therefore, 0.46 g of helium is equal to 0.46 g / 4 g/mol = 0.115 mol of helium in the balloon.
How many moles are in 30.8g of helium?
4 g of He = 1 mole. So, 30.8 g = 7.7 moles
How many moles are present in 0.12g of helium?
To calculate the number of moles in 0.12g of helium, you need to use the molar mass of helium. The molar mass of helium is approximately 4g/mol. Therefore, 0.12g of helium is equivalent to 0.12g / 4g/mol = 0.03 moles of helium.
How do you convert 26.7kg of helium into moles of helium?
To convert grams to moles, divide the given mass by the molar mass of helium. The molar mass of helium is approximately 4g/mol. Therefore, 26.7kg of helium is equal to 26,700g, which would be 6,675 moles of helium.
What is the mass of 18.8 moles of helium atoms?
1 mole of helium weighs 4.0026 g So. 18.8 of helium will weigh 75.25 g
What is the mass in grams of 1.5 moles of helium?
The mass of 1,5 moles of helium is 6,003 903 g.
