What is the gram molecular mass of a compound if 5 moles of the compound has a mass of 100 grams?
To find the gram molecular mass of the compound, you can use the formula: mass = moles × gram molecular mass. Given that 5 moles of the compound have a mass of 100 grams, you can rearrange the formula to find the gram molecular mass: gram molecular mass = mass / moles. Thus, gram molecular mass = 100 grams / 5 moles = 20 grams per mole.
What is the gram mass of compound if 5 moles of the compound has a mass of 100 grams?
The molar mass is 20 g.
How many grams are in 0.056 moles of neon?
To convert moles to grams, you need to use the molar mass of the element. The molar mass of neon is approximately 20.18 g/mol. Given that 0.056 moles of neon are present, you can calculate the grams by multiplying 0.056 moles by the molar mass of neon to get approximately 1.13 grams of neon.
How many grams of iron are in 20 moles of carbon monodxide?
In carbon monoxide (CO), the molar ratio of carbon (C) to oxygen (O) is 1:1. Therefore, in 20 moles of CO, there are 20 moles of carbon. The molar mass of carbon is approximately 12.011 g/mol, so in 20 moles of carbon, there are 20 x 12.011 = 240.22 grams of carbon.
How many moles in 20g of magnesium nitrate?
There are 0.13 moles in 20 grams of magnesium nitrate.
What mass of oxygen is required to completely react with 20 grams of CH4?
To calculate the mass of oxygen required to react with 20 grams of CH4, we first need to write and balance the chemical equation for the reaction. The balanced equation for the combustion of CH4 is: CH4 + 2O2 → CO2 + 2H2O This equation tells us that 1 mole of CH4 reacts with 2 moles of O2. The molar mass of CH4 is 16 g/mol. Therefore, 20 grams of CH4 is equal to 20/16 = 1.25 moles CH4. So, 1.25 moles of CH4 would require 2.50 moles of O2. The molar mass of O2 is 32 g/mol. Therefore, the mass of O2 required would be 2.50 moles * 32 g/mol = 80 grams.
What is the gram molecular mass of a compound if 5 moles of the compound has a mass of 100 grams?
To find the gram molecular mass of the compound, you can use the formula: mass = moles × gram molecular mass. Given that 5 moles of the compound have a mass of 100 grams, you can rearrange the formula to find the gram molecular mass: gram molecular mass = mass / moles. Thus, gram molecular mass = 100 grams / 5 moles = 20 grams per mole.
Which value most closely represents the number of grams in 20 moles of carbon?
The number of grams in 20 moles of carbon is 240,22 g.
20 grams of NaOH to moles?
To convert grams of NaOH to moles, you need to divide the given mass by the molar mass of NaOH. The molar mass of NaOH is approximately 40 g/mol (sodium: 23 g/mol, oxygen: 16 g/mol, hydrogen: 1 g/mol). Thus, 20 grams of NaOH is equivalent to 0.5 moles (20 g / 40 g/mol).
What is the gram mass of compound if 5 moles of the compound has a mass of 100 grams?
The molar mass is 20 g.
How many grams are in 0.056 moles of neon?
To convert moles to grams, you need to use the molar mass of the element. The molar mass of neon is approximately 20.18 g/mol. Given that 0.056 moles of neon are present, you can calculate the grams by multiplying 0.056 moles by the molar mass of neon to get approximately 1.13 grams of neon.
How much is 20 grams of sodium.?
The molar mass of sodium is approximately 23 g/mol. Therefore, 20 grams of sodium would be equivalent to about 0.87 moles of sodium.
What is the mass in grams of 7.50 and times1020 molecules of caffeine C8H10N4O2?
To calculate the mass in grams of 7.50 x 10^20 molecules of caffeine (C8H10N4O2), you need to determine the molar mass of caffeine and then convert the number of molecules to moles using Avogadro's number. Finally, multiply the moles of caffeine by the molar mass to find the mass in grams.
How many grams of iron are in 20 moles of carbon monodxide?
In carbon monoxide (CO), the molar ratio of carbon (C) to oxygen (O) is 1:1. Therefore, in 20 moles of CO, there are 20 moles of carbon. The molar mass of carbon is approximately 12.011 g/mol, so in 20 moles of carbon, there are 20 x 12.011 = 240.22 grams of carbon.
How many moles of lithium hydroxide are required to react with 20 mol of CO2?
The balanced chemical equation for the reaction of lithium hydroxide with carbon dioxide is 2 LiOH + CO2 -> Li2CO3 + H2O. The mole ratio of LiOH to CO2 is 2:1, meaning that 40 moles of LiOH are required to react with 20 moles of CO2.
How many grams of LiCl would you use to make 20 ml of a 4M solution?
To make a 4M solution in 20 ml, you would need 0.32 grams of LiCl. This can be calculated using the formula: moles = molarity x volume (in L), then converting moles to grams using the molar mass of LiCl.
