How many grams is 0.5 moles of sodium bicarbonate?
The molar mass of sodium hydrogen carbonate is 84 grams per mole, therefore 0.5 moles of it weighs 42 grams.
How many moles in 25 grams of NaCl?
To calculate the number of moles in 25 grams of NaCl, divide the given mass by the molar mass of NaCl. The molar mass of NaCl is approximately 58.44 g/mol. Therefore, 25 grams of NaCl is equivalent to approximately 0.43 moles.
How many grams are in 4.20 mol of sodium chloride?
To find the grams in 4.20 mol of sodium chloride, you need to calculate the molar mass of sodium chloride (NaCl), which is approximately 58.44 g/mol. Multiply this molar mass by 4.20 mol to get the grams: 58.44 g/mol * 4.20 mol = 245.808 g. Therefore, 4.20 mol of sodium chloride would be approximately 245.808 grams.
What is the mass of K 42 remaining in a 16g sample of 37.2hrs?
To find the mass of K-42 remaining after 37.2 hours, we would need additional information such as the half-life of K-42. Without this information, it is not possible to calculate the remaining mass.
Calculate the number of neutrons of the atom whose atomic number is 42 and whose mass number is 96?
To find the number of neutrons, subtract the atomic number (number of protons) from the mass number. For this atom with an atomic number of 42 and a mass number of 96, the number of neutrons would be 96 - 42 = 54 neutrons.
How many moles are in 42 grams of CO2?
To calculate the number of moles in 42 grams of CO2, we first need to find the molar mass of CO2, which is approximately 44 grams per mole. Then, divide the given mass by the molar mass to find the number of moles. In this case, 42 grams of CO2 is equivalent to 42/44 = 0.955 moles.
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 moles of nitrogen in 42 grams of nitrogen?
As a rule of thumb, the atomic mass of an element equals the number of grams of that element equals a mole. Since the atomic mass of Nitrogen is 14, there are 14 grams in one mole of Nitrogen. Next, we just have to divide 42 by 14 and we get our answer: There are 2.9988 moles in 42 grams of Nitrogen.
How do youcalculate density 28 ml that has a mass of 42 grams?
Density = (mass) / (volume) = 42/28 =1.5 gm/cm3
What is the mass of water displaced when a 42 cm 3 piece of silver is submerged in water?
nominally 42 grams
How many grams is 0.5 moles of sodium bicarbonate?
The molar mass of sodium hydrogen carbonate is 84 grams per mole, therefore 0.5 moles of it weighs 42 grams.
What is 42 mL in grams?
This is not a valid conversion; milligrams (mg) and grams (g) are measures of weight or mass and mL (milliliters) is a measure of volume.
What is the density of a cube that has a mass of 42 grams and a volume of 7cm3 show your work?
Density = (mass) divided by (volume) = (42) divided by (7) = 6 grams per cm3 . Next time, it'll be a lot easier if you just have your teacher contact us directly.
How many grams in 42 kg?
1 kilogram = 1,000 grams 42 kilograms = 42,000 grams
How many grams are in 42 kilograms?
There are 1000 grams in one kilogram. Therefore, 42 kilograms is equal to 42 x 1000 = 42000 grams.
How many moles in 25 grams of NaCl?
To calculate the number of moles in 25 grams of NaCl, divide the given mass by the molar mass of NaCl. The molar mass of NaCl is approximately 58.44 g/mol. Therefore, 25 grams of NaCl is equivalent to approximately 0.43 moles.
