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%
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.
How do you figure the mass of 1 mL of water?
The mass of 1 mL of water is 1 g.
How many moles are present in 1 g of ammonia nh3?
To find the number of moles in 1 g of ammonia (NH₃), first calculate its molar mass. The molar mass of NH₃ is approximately 17 g/mol (14 g/mol for nitrogen and 3 g/mol for hydrogen). Using the formula for moles (moles = mass/molar mass), we can calculate: 1 g NH₃ × (1 mol / 17 g) ≈ 0.059 moles of NH₃.
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.
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.
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 .
1liter of water has a mass of 1kg. Find the mass of a bottle filled with 1.5 liters of water if the bottle has a mass of 150g.?
To find the total mass of the bottle filled with water, you first calculate the mass of the water. Since 1 liter of water has a mass of 1 kg, 1.5 liters of water will have a mass of 1.5 kg, which is equivalent to 1500 g. Adding the mass of the empty bottle (150 g) to the mass of the water (1500 g), the total mass is 1500 g + 150 g = 1650 g. Thus, the mass of the bottle filled with 1.5 liters of water is 1650 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.
