What is the density of an object with a volume of 10ml and a mass of 20 grams?

Density = Mass / Volume So, density of an object with a volume of 10ml and a mass of 20 grams is = m / v = 20grams/10ml = 2g/ml


How many milliliters in 20grams?

Milliliters is volume and grams is mass, so you need to know mass density to solve this. For water, it has mass density of 1 gram per cubic centimeter which is the same as 1 gram per millitre of volume. So for water only, 20 ml = 20 grams.


A pumpkin seed has a mass of 250mgAbout how many pumpkin seed would it take to make a total mass of 10grams?

To find out how many pumpkin seeds are needed, divide the total mass by the mass of one pumpkin seed. In this case, 10 grams is 10,000 milligrams. So, 10,000 mg (total mass) / 250 mg (mass of one seed) = 40 pumpkin seeds needed to make a total mass of 10 grams.


What is the mass of exactly 150 gumballs?

The mass of 150 gumballs would depend on the average mass of one gumball. To find the total mass, you would multiply the mass of one gumball by 150. For example, if each gumball weighs 1 gram, then the total mass would be 150 grams.


If one thousand seeds have the mass of 200 grams how many gams does one seed have?

To find the mass of one seed, you would divide the total mass of the seeds (200 grams) by the total number of seeds (1000). Therefore, each seed would have a mass of 0.2 grams (200 grams / 1000 seeds = 0.2 grams per seed).


What would be the total mass of 100 carbon atoms selected at random?

The atomic mass of carbon is approximately 12 atomic mass units. Therefore, the total mass of 100 carbon atoms would be 100 * 12 = 1200 atomic mass units.


What would be the total mass of the products of a reaction in which 10 grams of water decomposes into the elements of hydrogen and oxygen?

The total mass of the products would be 10 grams, as mass is conserved in a chemical reaction. When water decomposes into its elements, hydrogen and oxygen, the total mass of the products will be the same as the mass of the reactant.


How do you find the mass of an object If the mass of the beaker is 15grams and the total weight is 30.100grams?

Subtract the mass of the beaker from the total weight.


How many grams of NaCl would you have if you had 3.7 moles of NaCl?

Molar mass of Na = 22.9898g/mol Molar mass of Cl = 35.45g/mol Total molar mass = 58.4398g/mol 58.4398g * 3.7mol =216.22726g


How do you find how many moles are in a solute?

Yoy need to know the molar mass of this solute and the mass of the solute:moles = total mass/molar mass


What is the mass percent of oxygen in the compound?

To determine the mass percent of oxygen in a compound, you would calculate the mass of oxygen in the compound and then divide it by the total mass of the compound, before multiplying by 100. The formula is: (mass of oxygen in compound / total mass of compound) x 100%.


What is total mass?

The mass of an object can be expressed in mass per unit or in total mass. Total mass represent the full amount.
