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 many grams in 42 kg?
1 kilogram = 1,000 grams 42 kilograms = 42,000 grams
What is the density of an object that has a mass of 98 grams and a volume of 42 milliliters?
Density = (mass) / (volume) = 2.33 gram/cc(rounded)Note: The 'ml' and the 'cc' are identical volumes.
42 grams equals how many kilograms?
One kilogram = 1000 grams Therefore 42g = 42 divided by 1000 = 0.042kg
What density of an object with a volume of 15 ml and a mass of 42 grams?
Density of that object is 2.8
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 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.
What is 42 grams of diatomic oxygen in moles?
moles = mass/molar mass The molar mass of an oxygen atom = 16 g mol-1, as there are two oxygen atoms in diatomic oxygen this has to be doubled. 42g / 32g mol-1 = 1.3125 moles
What is the number of moles in 42 g of NaCl?
To find the number of moles in 42 g of NaCl, divide the given mass by the molar mass of NaCl. The molar mass of NaCl is approximately 58.5 g/mol (sodium's atomic weight is 23 and chlorine's is 35.5). So, 42 g / 58.5 g/mol ≈ 0.72 moles of NaCl.
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 do you Convert 42 grams AlOH3 to moles AlOH3?
That is aluminum hydroxide and as a polyatomic ion hydroxide needs to be in parenthesis. Thus; Al(OH)3 This shows aluminum's 3+ oxidation state and the three matching hydroxides 1- state. 42 grams Al(OH)3 ( 1 mole Al(OH)3/78.004 grams) = 0.538 moles Al(OH)3 As significant figures require; 0.54 moles Al(OH)3
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.
