How many moles in 20g of magnesium nitrate?
There are 0.13 moles in 20 grams of magnesium nitrate.
What is the percent by mass of NaCl in a solution containing 20g of NaCl dissolved in 600g of H2O?
9%
How many moles of B in 20g of borax?
To calculate the number of moles in 20g of borax (Na2B4O7), we first need to find the molar mass of borax. By adding the atomic masses of all the elements in borax, we get a molar mass of approximately 201.22 g/mol. Then, we use the formula: moles = mass / molar mass. Substituting in the values, we find that there are approximately 0.10 moles of borax in 20g. Since there are four boron atoms in one molecule of borax, the number of moles of B (boron) would be 0.10 moles * 4 = 0.40 moles.
How many moles of so3 are in 20g of so3?
To find the number of moles, you first need to calculate the molar mass of SO3, which is 80.06 g/mol. Then, you can use the formula: moles = mass / molar mass. Thus, for 20g of SO3, you would have 20g / 80.06 g/mol = 0.25 moles of SO3.
What is the density of a mineral sample with a mass of 20g and a volume of 12cm3?
The density of the mineral sample is 1.67 g/cm3. This is calculated by dividing the mass (20g) by the volume (12cm3).
How many moles in 20g of sodium hydroxide?
To determine the number of moles in 20g of sodium hydroxide, you need to divide the given mass by the molar mass of sodium hydroxide. The molar mass of NaOH is 40 g/mol (sodium: 23 g/mol, oxygen: 16 g/mol, hydrogen: 1 g/mol). So, 20g NaOH / 40 g/mol = 0.5 moles of sodium hydroxide.
Which has more molecules 16g of CO or 20g of N2?
There are 6.023x10^23 molecules in one mole of a compound. So now, you have to find how many moles of each compound you have. CO's molecular weight is (12+16) = 28 g/mol N2's molecular weight is (14+14) = 28 g/mol So you find the moles of each. moles of N2 = 20g/ 28g/mol = .714 moles moles of CO = 16g / 28 g/mol = .571 moles So, N2 has (.714 *6.023x10^23) has 4.3 x10^23 molecules and CO (.571 *6.023x10^23) has 3.4x10^23 molecules. So, 20g of N2 has more molecules than 16g of CO
How many moles are in 3 moles of HF?
Moles = Mass/Molar Mass.Using this equation, we can take 25/(1.0 + 19) and find that it is equal to 1.25 moles.Keep in mind that very few significant figures were used for this example (2), and that if accuracy is to be expected, as many as possible should be used.
What is the percent of mass nacl in a solution containing 20g of nacl dissolved in 600g of h2o?
If You do that experiment under standard conditions, the weight of 100 ml water will be 100 g. The mass of the total system is 120 g in that case and the NaCl contributes to it with 20/120*100 mass percent.Thus the answer is 16.67 %.
What is the half-life of a radio slope if a 20g sample becomes 5g after 2 days?
1 day
What is the volume of a sample that has a mass of 20g and a density of 4 g ml?
The volume of the sample whose mass is 20 g and density is 4 g/ml is 5 milliliters.
How many atoms of nitrogen are in 20g of NH4NO3?
To find the number of atoms of nitrogen in 20g of NH4NO3, first calculate the molar mass of NH4NO3 (80.043 g/mol). Next, divide the mass of NH4NO3 by its molar mass to find the number of moles (0.2496 mol). Finally, multiply the number of moles by Avogadro's number (6.022 x 10^23) to determine the number of atoms of nitrogen (1.50 x 10^23 atoms).
