What is the mass in grams of 0.0135 mole of the element Na?
molar mass Na = 22.99g/mol (atomic weight in grams) 0.0135mol Na x (22.99g/mol) = 0.310g Na
What is the molar mass of NaC2H3O2.3H2O?
The molar mass of NaC2H3O2.3H2O is calculated by adding the individual molar masses of its components - sodium (Na), carbon (C), hydrogen (H), oxygen (O), and water (H2O). The molar mass is found to be 136.08 g/mol.
What is the molar mass of sodium and hydroxide?
The molar mass of sodium (Na) is 22.99 g/mol, and the molar mass of hydroxide (OH) is 17.01 g/mol. To find the molar mass of sodium hydroxide (NaOH), you can add the molar masses of sodium and hydroxide together, which equals 39.00 g/mol.
What is the mass of 9 moles of sodium?
The molar mass of sodium (Na) is approximately 22.99 g/mol. To find the mass of 9 moles of sodium, you would multiply the molar mass by the number of moles: 22.99 g/mol * 9 mol = 206.91 grams. Therefore, the mass of 9 moles of sodium is approximately 206.91 grams.
How many grams of sodium are in a 1 mole sample of sodium?
The molar mass of an element corresponds to the atomic mass of the element (found on the periodic table). The atomic mass of Sodium-Na is 22.990 g, which is also the molar mass of Na. So for 1 mole of Na, there are 22.990 grams of Na. If we had 3 moles of Na, then we would simply multiply the molar mass by 3.
What is the mass in grams of 0.0135 mole of the element Na?
molar mass Na = 22.99g/mol (atomic weight in grams) 0.0135mol Na x (22.99g/mol) = 0.310g Na
How many moles of Na are in 15 g of NaCl?
To find the number of moles of Na in 15 g of NaCl, you first need to calculate the molar mass of NaCl, which is 58.44 g/mol. Since Na makes up 39.34% of the molar mass of NaCl, you can calculate the moles of Na as (15 g / 58.44 g/mol) * 0.3934 = 0.255 moles of Na.
What is the mass in grams of 0.15 moles sodium?
The molar mass of sodium (Na) is 22.99 g/mol. To find the mass in grams of 0.15 moles of sodium, you can use the formula: mass = moles x molar mass. Therefore, the mass of 0.15 moles of sodium is 0.15 mol x 22.99 g/mol = 3.4485 grams.
How many moles of Na are in 42 grams of Na?
To find the number of moles of Na in 42 grams, we can use the molar mass of Na, which is approximately 23 grams/mol. First, calculate the number of moles by dividing the given mass by the molar mass: 42 grams / 23 grams/mol = 1.83 moles of Na.
How many grams of NaCl would you have if you had 3.7 moles of NaCl?
Molar mass of Na = 22.9898g/mol Molar mass of Cl = 35.45g/mol Total molar mass = 58.4398g/mol 58.4398g * 3.7mol =216.22726g
What is the mass in grams of 3.25 mol of Na-Cl?
To find the mass of 3.25 moles of NaCl, first calculate the molar mass of NaCl. Sodium (Na) has a molar mass of approximately 22.99 g/mol, and chlorine (Cl) has a molar mass of about 35.45 g/mol, giving NaCl a total molar mass of about 58.44 g/mol. Therefore, the mass of 3.25 moles of NaCl is calculated as follows: 3.25 mol × 58.44 g/mol = 190.38 grams.
What is the molar mass of NaC2H3O2.3H2O?
The molar mass of NaC2H3O2.3H2O is calculated by adding the individual molar masses of its components - sodium (Na), carbon (C), hydrogen (H), oxygen (O), and water (H2O). The molar mass is found to be 136.08 g/mol.
What is the molar mass of sodium and hydroxide?
The molar mass of sodium (Na) is 22.99 g/mol, and the molar mass of hydroxide (OH) is 17.01 g/mol. To find the molar mass of sodium hydroxide (NaOH), you can add the molar masses of sodium and hydroxide together, which equals 39.00 g/mol.
What is the mass of 0.71 mol Na?
Mass of Na = amount of Na x atomic mass = 0.71 x 23.0 = 16.3g
A chemist requires 0.893 mol Na2CO3 for a reaction. How many grams does this correspond to?
To find the mass of 0.893 moles of Na₂CO₃, we first calculate its molar mass. The molar mass of Na₂CO₃ (sodium carbonate) is approximately 105.99 g/mol. Therefore, the mass can be calculated using the formula: mass = moles × molar mass, which gives us 0.893 mol × 105.99 g/mol = 94.55 grams. Thus, 0.893 moles of Na₂CO₃ corresponds to approximately 94.55 grams.
What is the mass percent of sodium in Na2CO3 the molar mass of Na2CO3 is 106gmole?
The molar mass of Na2CO3 is 106 g/mol. The molar mass of sodium in Na2CO3 is 2 * 23 g/mol = 46 g/mol. To calculate the mass percent of sodium in Na2CO3, we divide the molar mass of sodium by the molar mass of Na2CO3 and multiply by 100: (46 g/mol / 106 g/mol) * 100 ≈ 43.4%.
What is the mass of 9 moles of sodium?
The molar mass of sodium (Na) is approximately 22.99 g/mol. To find the mass of 9 moles of sodium, you would multiply the molar mass by the number of moles: 22.99 g/mol * 9 mol = 206.91 grams. Therefore, the mass of 9 moles of sodium is approximately 206.91 grams.
