What amount of helium is 0.54 g?
Moles = weight in grams / atomic weight So the moles in 0.54 g of He = 0.54 / 4.002 = 0.14 moles
What is the amount in moles in each elemental sample 11.8 g Ar 3.55 g Zn 26.1 g Ta 0.211 g Li?
To find the number of moles in each elemental sample, we use the formula: moles = mass (g) / molar mass (g/mol). Argon (Ar): ( \text{molar mass} = 39.95 , \text{g/mol} ), so ( \text{moles} = 11.8 , \text{g} / 39.95 , \text{g/mol} \approx 0.295 , \text{mol} ). Zinc (Zn): ( \text{molar mass} = 65.38 , \text{g/mol} ), so ( \text{moles} = 3.55 , \text{g} / 65.38 , \text{g/mol} \approx 0.0543 , \text{mol} ). Tantalum (Ta): ( \text{molar mass} = 180.95 , \text{g/mol} ), so ( \text{moles} = 26.1 , \text{g} / 180.95 , \text{g/mol} \approx 0.144 , \text{mol} ). Lithium (Li): ( \text{molar mass} = 6.94 , \text{g/mol} ), so ( \text{moles} = 0.211 , \text{g} / 6.94 , \text{g/mol} \approx 0.0304 , \text{mol} ).
How many kilograms are there in 261 grams?
261 g = 0.261 kgTo convert from g to kg, divide by 1000.
How many moles are I am 223.2 g iron (Fe)?
To find the number of moles of iron (Fe) in 223.2 g, you can use the formula: moles = mass (g) / molar mass (g/mol). The molar mass of iron is approximately 55.85 g/mol. Thus, moles of iron = 223.2 g / 55.85 g/mol ≈ 3.99 moles.
Which is heavier 5 moles of carbon or 5 moles of sodium?
5 moles of carbon is 60,055 g.5 moles of sodium is 114,949 g.
How many mole in 0.0073 kg of Ta?
To find the number of moles in 0.0073 kg of Ta (tantalum), we need to use the molar mass of Ta, which is approximately 180.95 g/mol. First, convert the mass to grams (0.0073 kg = 7.3 g), then divide by the molar mass to find the number of moles. 7.3 g / 180.95 g/mol ≈ 0.04 mol of Ta.
What amount of helium is 0.54 g?
Moles = weight in grams / atomic weight So the moles in 0.54 g of He = 0.54 / 4.002 = 0.14 moles
What is the amount in moles of 3.80g Zn?
To find the amount in moles of 3.80g of zinc (Zn), you need to divide the mass by the molar mass of Zn, which is approximately 65.38 g/mol. 3.80g Zn / 65.38 g/mol ≈ 0.058 moles Zn
What is the amount in moles of 3.45 g Zn?
Calculated by dividing mass (in grams) by atomic mass of Zn: 3.45(g) / 65.38(g/mole) = 0.0528 mole
Which statement shows how to correctly convert from the mass of a compound in grams to the amount of that compound in moles?
To convert from the mass of a compound in grams to the amount of that compound in moles, you need to divide the mass of the compound in grams by its molar mass (which is found on the periodic table). This will give you the number of moles of the compound. The formula to use is: moles = mass (g) / molar mass.
How many moles of NH3 can be produced by the reaction of 2.00 g of N2 with 3.00 g H2 Reaction N2(g) plus 3 H2(g) 2 NH3(g)?
To determine the limiting reactant, first convert the masses of N2 and H2 to moles. Then divide the amount of each reactant by its stoichiometric coefficient in the balanced equation to find moles of NH3 produced. The limiting reactant is the one that produces the least amount of NH3.
How many kilograms are there in 261 grams?
261 g = 0.261 kgTo convert from g to kg, divide by 1000.
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.
Calculate the amount in moles 16.3gSF6?
To calculate the amount in moles, you first need to determine the molar mass of SF6, which is 146.06 g/mol. Then, divide the given mass of 16.3g by the molar mass to find the amount in moles. In this case, 16.3g SF6 is equal to 0.112 moles.
How many moles are in 27.4 g of water?
27.4 g H2O x 1 mole/18 g = 1.52 moles
How many moles are I am 223.2 g iron (Fe)?
To find the number of moles of iron (Fe) in 223.2 g, you can use the formula: moles = mass (g) / molar mass (g/mol). The molar mass of iron is approximately 55.85 g/mol. Thus, moles of iron = 223.2 g / 55.85 g/mol ≈ 3.99 moles.
