What is the mass percent of sodium chloride in a solution prepared by adding 1 g of sodium chloride to 50 g of water?
The mass percent of sodium chloride can be calculated as follows: Mass of NaCl = 1 g Mass of water = 50 g Total mass of solution = 1 g + 50 g = 51 g Mass percent of NaCl = (Mass of NaCl / Total mass of solution) x 100% = (1 g / 51 g) x 100% ≈ 1.96%
How do you figure the mass of 1 mL of water?
The mass of 1 mL of water is 1 g.
What is gram formula mass of KNO3?
Mass of KNO3 K = 1 * 39.10 g = 39.10 g N = 1 * 14.01 g = 14.01 g O = 3 * 16.00 g = 48.00 g Total = 101.11 g The molar mass of potassium nitrate is 101.11 grams.
A sample of 1 mL of water has a mass of about?
The mass of 1 mL of water is 1 g.
What is the mass of 1 cm3 of water?
The mass of 1 cm3 of water is approximately 1 gram.
What is the mass equivalent of 1 ml of distilled water?
Since each ml of water weights 1 g, 0.1 liters of water = 100 grams. So 1 kilogram (kg) is equal to 1000 grams. This means 100 g = 0.1 kg.
How much mass is in 1 mole of sulfur atoms?
Remember the Equation Moles = mass(g) / Ar (Relative Atomic Mass) Algebraically rearranging mass(g) = moles X Ar We have 1 mole and from the Periodic Table the Atomic Mass of Sulphur is '32'. Hence substituting mass(g) = 1 moles X 32 mass = 32 g .
How many moles are there in 98.1 g of H2SO4?
To find the number of moles in 98.1 g of H2SO4, first calculate the molar mass of H2SO4 (98.1 g/mol). Then, divide the given mass by the molar mass to find the number of moles (98.1 g / 98.1 g/mol = 1 mol). Therefore, there is 1 mole in 98.1 g of H2SO4.
How many moles in 1 g of zinc nitrate?
To determine the number of moles in 1 g of zinc nitrate, you need to know the molar mass of zinc nitrate. Zinc nitrate has a molar mass of 189.36 g/mol. By dividing 1 g by the molar mass, you can calculate that there are approximately 0.0053 moles of zinc nitrate in 1 g.
What is the molar mass of Zn2SO4?
The molar mass of zinc sulfate - ZnSO4 - is 161,47 g.
What is the mass of 1 moles of CH2Cl2?
The molar mass of dichlormethane is 84,93 g.
What is the mass of 2 moles of water (H2O)?
A mole of HNO3 weighs 63g (1 + 14 +16x3). Therefore, two moles weigh, 2 x 63 =126 g
