How many moles is 1.346g of Mg?
To find the number of moles in 1.346g of Mg, you need to divide the mass by the molar mass of Mg (24.305 g/mol). 1.346g Mg / 24.305 g/mol = 0.055 moles Mg
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.

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?
To find the number of moles in 202 grams of Mg, divide the given mass by the molar mass of Mg (24.305 g/mol). Number of moles = 202 grams / 24.305 g/mol ≈ 8.31 moles.
How do you calculate the number of moles in 4.637 grams in Mg?
To calculate the number of moles in a sample of magnesium (Mg), you first need to determine its molar mass. Magnesium has a molar mass of approximately 24.305 g/mol. Then, divide the given mass (4.637 grams) by the molar mass to find the number of moles. In this case, 4.637 g ÷ 24.305 g/mol ≈ 0.191 moles of Mg.
HOW MANY moles of mg atom are there in 100 gm of mg?
There are 2.47 moles of Mg atoms in 100 g of Mg. This is calculated by dividing the given mass by the molar mass of Mg (24.305 g/mol) to get the number of 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.
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?
To find the number of moles in 13.2 grams of magnesium, divide the mass of magnesium by its molar mass. The molar mass of magnesium is approximately 24.31 g/mol. So, 13.2 g / 24.31 g/mol ≈ 0.54 moles of magnesium.
109.4g Mg contains how many moles?
To determine the number of moles in 109.4g of Mg, divide the given mass by the molar mass of Mg. The molar mass of Mg is approximately 24.305 g/mol. Therefore, 109.4g of Mg will contain approximately 4.5 moles.
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.
