Density is the mass per unit volume. e.g. kg/m3.
But you've only given one of the quantities needed - we still need the volume of the sphere.
To find the volume of the sphere, you need to know the density of the material the sphere is made of. With just the mass provided (75 grams), you cannot calculate the volume without this additional information.
Density is Mass/Volume (kg/m3) The volume of a sphere is given byV= (4/3)*pi*r3 181.8 grams = 0.1818 kg 7.15 cm = 0.0715 m V = (4/3)*pi*(0.0715/2)3 = 1.91*10-4 m3 Therefore, Density = 0.1818/1.91*10-4 = 949.8 kg/m3
To find the number of moles in 5000 grams of calcium, you need to divide the given mass by the molar mass of calcium. The molar mass of calcium is approximately 40.08 g/mol. So, 5000 grams of calcium is equal to 5000/40.08 = 124.69 moles of calcium.
I assume the correct units for the density is 3.14 grams per milliliter. So if you have 93.5 grams of a substance with a density of 3.14 grams per milliliter, then you divide the mass by the density to find volume. 93.5 grams/3.14 grams/ml = 29.77 ml
To find the density, divide the mass of the rock (15 grams) by its volume (30 milliliters). Density = mass/volume, so in this case 15 grams / 30 milliliters = 0.5 grams per milliliter. Therefore, the density of the rock is 0.5 g/mL.
To find the volume of the sphere, you need to know the density of the material the sphere is made of. With just the mass provided (75 grams), you cannot calculate the volume without this additional information.
how do you find the mass of a sphere Volume x density => 4/3(pi)(r)3 x density
To find density, divide the mass by the volume. In this case, the density would be 55.6 grams divided by 3.2, which equals 17.375 grams per cubic centimeter.
Density is Mass/Volume (kg/m3) The volume of a sphere is given byV= (4/3)*pi*r3 181.8 grams = 0.1818 kg 7.15 cm = 0.0715 m V = (4/3)*pi*(0.0715/2)3 = 1.91*10-4 m3 Therefore, Density = 0.1818/1.91*10-4 = 949.8 kg/m3
To find the number of moles in 5000 grams of calcium, you need to divide the given mass by the molar mass of calcium. The molar mass of calcium is approximately 40.08 g/mol. So, 5000 grams of calcium is equal to 5000/40.08 = 124.69 moles of calcium.
you have to divide the mass by the volume then measure the ends then you found your answer
To find the radius of the aluminum sphere, you need to know its density. Without density information, it's not possible to calculate the radius just from the mass given.
Volume of anything = (its mass) divided by (its density) regardless of what shape it happens to be.
Density = mass / volume. You have the density of aluminum and the mass of the aluminum sphere. The volume of a sphere is 4/3*Pi*r^3. Therefore volume = 4/3*Pi*r^3 = mass / density. Solve for r, which is the radius of the sphere.
Density= mass/volume volume = mass/density
calculate the volume using the formula: Vsphere = (4/3)*pi*r^3 then calculate density by Density = Mass/Volume
the mass is the 50 grams you probably need the volume volume = mass / density get the density from tables
