How many moles is 1.346g of Mg?
1.346 grams Mg (1 mole Mg/24.31 grams) = 0.05537 moles magnesium
What is the number of moles of magnesium in a strip of magnesium with a mass of 0.1126g?
To find the number of moles of magnesium, we first need to calculate the molar mass of magnesium, which is 24.305 g/mol. Next, we convert the mass of the strip to moles using the formula moles = mass/molar mass. Plugging in the values, the number of moles of magnesium in the strip is 0.00463 moles.
How many moles are in 1.2 mg of oxygen?
The molar mass of oxygen is 32 g.1,2 mg oxygen is equal to 0,0000375 moles.
How many moles are in 29.4mg of BrI?
To find the number of moles, you first need to convert 29.4 mg of BrI to grams by dividing by 1000 to get 0.0294 g. Next, calculate the number of moles by dividing the mass in grams by the molar mass of BrI (which is 207.8 g/mol). Therefore, there are approximately 0.000141 moles of BrI in 29.4 mg.
What is mass of 1.5 moles of magnesium?
Molar mass of magnesium is 24gmol-1. mass of 1.5 mg mole 36g.
What mass (in mg) does 2.63 moles of nickel have?
1.54 x 105 mg
How many moles is 1.346g of Mg?
1.346 grams Mg (1 mole Mg/24.31 grams) = 0.05537 moles magnesium

If 0.0276 g of Mg reacts with HCl how many moles of gas produced?
To calculate the moles of gas produced, first find the moles of Mg reacting by dividing the mass by the molar mass of Mg. Next, determine the mole ratio of Mg to gas produced from the balanced chemical equation of the reaction. Finally, multiply the moles of Mg by the mole ratio to find the moles of gas produced.
How many moles are in 202 grams of Mg?
Use the formulae n=m/M Where, n - number of mols m - mass M - molar mass Molar mass of Mg = 24 n=202/24 = 8.416
How do you calculate the number of moles in 4.637 grams in Mg?
For this you need the atomic mass of Mg. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel.4.637 grams Mg / (24.3 grams) = .191 moles Mg
HOW MANY moles of mg atom are there in 100 gm of mg?
The atomic weight of magnesium is 24.31; therefore, the number of moles in 100 gm is 100/24.31 = 4.11, to the justified number of significant digits.
How many moles are in 1.2 mg of oxygen?
The molar mass of oxygen is 32 g.1,2 mg oxygen is equal to 0,0000375 moles.
What is the mass of HCl that would be required to completely react with 5.2 grams of Mg?
The balanced chemical equation for the reaction between HCl and Mg is: Mg + 2HCl -> MgCl2 + H2. One mole of Mg reacts with 2 moles of HCl. Calculate the moles of Mg in 5.2 grams using the molar mass of Mg. Then use the mole ratio to find the moles of HCl needed, and finally calculate the mass of HCl using its molar mass.
How many moles are in 13.2 grams of magnesium?
For this you need the atomic mass of Mg. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. Mg= 24.3 grams35.0 grams Mg / (24.3 grams) = 1.44 moles Mg
109.4g Mg contains how many moles?
The number of moles is equal to the mass divided by the molar mass. In mathematical form, it is:Moles = Mass of Mg / Molar Mass of MgMoles = 109.4 / 24.3Moles = 4.501 (rounded to three decimal points)Always keep a Periodic Table handy, molar masses are quite important.
How many moles of sodium borohydride are used in 100 mg?
To calculate the number of moles of sodium borohydride in 100 mg, you need to know the molar mass of the compound, which is 37.83 g/mol. First, convert 100 mg to grams (0.1 g), then divide by the molar mass to get the number of moles, which is approximately 0.0026 moles.
