How many moles are present in gram's of silicon Si?
1 g silicon is equal to 0,0356 moles.
How many grams are in 6.3 moles of BH3?
6.3(mol) * 13.83 (g·mol−1)= 87.1 gram BH3
How many moles are present in 1 g?
It depends on the substance. Remember that moles are a unit of amount, and one mole is 6.02 × 1023 atoms. So if you have lead and hydrogen, they are obviously going to weigh differently. It would take far fewer atoms of lead to amount to 1 gram; therefore, less moles. However, one hydrogen atom has far less mass than one lead atom, and would need more atoms (and moles) to make one gram.
How many milligrams are in 1 gram of copper?
1 gram of copper is in 1 gram of copper.
How many atoms are in 1 gram of boron?
To find the number of atoms in 1 gram of boron, we first need to know its molar mass, which is approximately 10.81 grams per mole. Using Avogadro's number, which is about (6.022 \times 10^{23}) atoms per mole, we can calculate the number of atoms in 1 gram of boron. The number of moles in 1 gram is (1 , \text{g} / 10.81 , \text{g/mol} \approx 0.0925 , \text{moles}). Thus, the number of atoms is approximately (0.0925 \times 6.022 \times 10^{23} \approx 5.57 \times 10^{22}) atoms.
How many moles are in a gram of carbon?
1 gram carbon (1 mole C/12.01 grams) = 0.08 moles carbon ===============
How many moles are in 1 gram of H2O?
18 grams of water contain 1 mole. so 1 gram contains 1/18 moles of water.
How many moles are in the element uranium?
1 atom-gram of uranium = 238,02891 grams
How many moles are in gram of NaOH?
moles = mass/Mr moles = 100/(23+16+1) moles of NaOH = 2.5mol
How many moles are in 1 gram of graphite?
Graphite is a form of carbon, so the question is basically asking how many moles of carbon are in 18.0 grams of carbon. One gram of carbon contains 12.01 moles. This can be found on a periodic table. 18.0 grams of carbon must therefore have 18 times 12.01, or 216.18, moles of carbon.
How many gram of 34M of NaCL?
34 moles of NaCl is equivalent to 1 986,95 g.
How many anions are there in 2.50 g of MgBr2?
There are a total of 2 moles of anions in 2.50 g of MgBr2. Each formula unit of MgBr2 contains 2 moles of anions (Br-). The molar mass of MgBr2 is 184.113 g/mol, so 2.50 g is equivalent to 0.0136 moles, and therefore 0.0136 moles * 2 moles = 0.0272 moles of anions.
How many moles are present in gram's of silicon Si?
1 g silicon is equal to 0,0356 moles.
How many grams are in 6.3 moles of BH3?
6.3(mol) * 13.83 (g·mol−1)= 87.1 gram BH3
How many units per gram in KHP?
The molar mass of potassium hydrogen phthalate (KHP) is approximately 204.23 g/mol. Therefore, in 1 gram of KHP, there is approximately 0.00489 moles (1/204.23).
How many meters equals 1 hectare?

1 gram equals how many moles?
It depends on what the substance is. For the elements, the number given as the atomic weight for an element on the Periodic Table is also the number of grams/mole. For example, lithium has an atomic weight of 6.941, so one mole of lithium would be 6.941 grams of lithium. In theory you can have a mole of anything -- electrons, ions, shoes, dollar bills, cars, etc...
