Suppose an object weighs 15 g and has a volume of 5 cm what is the density of the object?
Note 5cm isn't a volume it is a length therefore for the answer we are assuming the volume is 5cm3 Density = mass/volume Density = 15g/5cm3 = 0.015kg/0.000005m3 Density = 3g/cm3 or in SI units 3,000kg/m3
How do you find the volume of 15 grams of ethanol?
Ethanol (USP grade) has a density of 0.810. From here we have to use the formula: d=m/v, where d is density, m, mass and v, volume. Solving for volume, we have v=m/d, therefore: v= 15/0.810 = 18.52 mL of ethanol are equivalent to 15g.
Is it possible to start with 5g of one chemical and 10g of another chemical make 15g of a third chemical?
No, it is not possible to start with 5g of one chemical and 10g of another and produce 15g of a third chemical due to the law of conservation of mass. This law states that mass cannot be created or destroyed in a chemical reaction; the total mass of the reactants must equal the total mass of the products. In this case, the maximum mass of the products can only equal the total mass of the reactants, which is 15g. However, the actual yield may be less than this due to side reactions or incomplete conversion.
How many molecules of sodium chloride in 15g of sodium chloride this atomic mass of sodium is 23gmol and of chlorine is 35gmol?
The formula unit of sodium chloride has the formula NaCl, showing that each molecular unit contains one atom of each of its constituent elements. Therefore, the mass of the formula unit is 23 plus 35 or 57 amu. Each amu for a compound contains Avagadro's number of molecules. Therefore, the answer to the problem is about (15/57) X 6.022 X 1023 = 4.3 X 1022.
What element is a halogen gas with a mass less than 25?
Fluorine, at 19 atomic mass units, is the only halogen gas that fits that requirement.
What is the density of an object that has a mass of 15g and a volume of 60ml?
Density = Mass/Volume = 15/60 = 0.25 grams per millilitre.
What is the density of an obbject with a volume of 10mL and a mass of 15g?
Density = Mass/Volume = 15/10 = 1.5 g per mL
What is the density of 15 g and a volume of 2 ml?
density = mass/volume = 15g/2mL = 7.5g/mL
Suppose an object weighs 15 g and has a volume of 5 cm what is the density of the object?
Note 5cm isn't a volume it is a length therefore for the answer we are assuming the volume is 5cm3 Density = mass/volume Density = 15g/5cm3 = 0.015kg/0.000005m3 Density = 3g/cm3 or in SI units 3,000kg/m3
What is the density of solid with a mass 150 grams and volume of 9.8cm?
density = mass/volume = 150g/9.8cm3 =~15.3g/cm3 =~15g/cm3 (assuming volume of 9.8cm means 9.8 cubic centimeters)
What is the density of a rock has a mass of 75 grams and a volume of 5 cubic centimeters?
15g/cm^3
What is the mass of a metal that has a density of 15g cm3 and a volume of 10 cm3?
m = mass rho = density V = volume rho = m/V m = rho * V = (15 g/cm^3) * (10 cm^3) = 150 g
How do you find the volume of 15 grams of ethanol?
Ethanol (USP grade) has a density of 0.810. From here we have to use the formula: d=m/v, where d is density, m, mass and v, volume. Solving for volume, we have v=m/d, therefore: v= 15/0.810 = 18.52 mL of ethanol are equivalent to 15g.
What is the calculation of the density if the mass of a solid material is measured 15 grams and its volume is measured 5 centimeters?
Denisty = mass / volume Density = 15g / 5cm3 Density = 3g per cm3 Once you know that the units of Density is g/cm3, you can use this to work out that you need to divide the mass (g) by volume (cm3) as can be seen in the units. This works for any equation you know the units for, like speed: Speed = m/s (meters/seconds) = distance/time
What is the density of Earth's inner core?
15g/cm3
What is the density of a carbon nucleus if you know the volume and molar mass?
Before we can go on to find the density of the carbon nucleus, we must find its mass. The given molar mass, which is the mass of 1 mole of a substance, indicates there's 12.00 grams of carbon for every 1 mole of carbon. What the question wants to know is the density of 1 carbon atom. Before we proceed to finding the carbon atom's density, the mass for 1 carbon atom must be found. To achieve this, we must divide the molar mass by Avogadro's number (aka Avogadro constant), or how many molecules are in 1 mole of a substance.Mass per atom = molar mass/Avogadro's number= 12.00 g mol-1/6.02 x 1023 mol= 1.99 x 10-23gNow we can proceed to find the density of the carbon nucleus, since we now know the mass for 1 carbon atom.Density= mass/volume= 1.99 x 10-23g/9.9 x 10-39mL= 2.0 x 10-15g/mL OR 2.0 x 10-15g/cm31 mL is equivalent to 1 g/cm3, making these 2 units interchangeable.By the way, another way to write g mol-1 is g/mol (the -1 indicates the divisor or can be read as "per").
What is the average density of the Earths inner core?
