What is the mass in mg of thanol of 5.1 1020 molecules of ethanol?
To calculate the mass of 5.1 x 10^20 molecules of ethanol, first determine the molar mass of ethanol (46.07 g/mol). Then convert this to mg/mol (46,070 mg/mol). Finally, multiply the molar mass by the number of molecules to find the total mass in mg (approximately 2.35 x 10^25 mg).
A magnesium atom has 12 protons and 12 neutrons what is its mass number?
The atomic number of magnesium is 12. Its nucleus must contain 12 protons and no electrons. The atomic number of an atom is determined by the number of protons. Electrons are not in the nucleus.
What is the mass in mg of 6 percent of calcium?
To find the mass of 6% calcium in mg, you need to know the total mass of the sample. Then, you multiply the total mass by 0.06 (6% as a decimal) to find the mass of calcium. Make sure to convert the result to milligrams for the final answer.
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
Mass of 3.65 mol Mg?
To solve this first the molar mass of Mg is needed (look at a periodic table). (Mg=23.0g/mol) Then convert the mols to grams as follows: (3.65 mol Mg) x (23.0 g/mol Mg) = 84.0 g Mg The mol units cancel in the conversion leaving only the gram units and the ammount in grams.
What is the mass number for the element Mg?
24.31
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 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
What is the mass in mg of thanol of 5.1 1020 molecules of ethanol?
To calculate the mass of 5.1 x 10^20 molecules of ethanol, first determine the molar mass of ethanol (46.07 g/mol). Then convert this to mg/mol (46,070 mg/mol). Finally, multiply the molar mass by the number of molecules to find the total mass in mg (approximately 2.35 x 10^25 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.
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.
What is the Mass Number of Mg2?
The mass number of Mg2 is 24, as magnesium (Mg) has an atomic number of 12 and Mg2 indicates the presence of two magnesium atoms, whose masses add up to 24.
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 mass of 1200 mg?
At the surface of the earth, mass = weight, so 1200 mg weight = 1200 mg mass
What is the mass in grams of 1.501023 atoms Mg?
This can be found using one of the most important constants for chemistry: Avogadro's number. According to wikipedia, the standard atomic weight of magnesium is 24.3050 grams per mole. Using Avogadro's number, we know there's 6.0221415 × 1023 atoms per mole, so if you divide the standard atomic weight of magnesium by Avogadro's number, you can get number of grams per atom of magnesium (i.e. the mass of a single magnesium atom in grams). (24.3050 g/mole) / (6.0221415 x 1023 atoms/mole) = 4.03564 g/atom
