What is the volume of 81 grams of aluminum?
The volume of 81 grams of aluminum can be calculated using its density, which is 2.7 g/cm^3. By dividing the mass (81 grams) by the density (2.7 g/cm^3), you can find that the volume of 81 grams of aluminum is approximately 30 cm^3.
What is a mass of a solid aluminuim block with a volume of 30 cm?
A centimetre is a measure of length in 1-dimensional space so nothing can have a volume of 30 cm.A block of aluminium, with a volume of 30 cubiccentimetres, has a mass of 81 grams.
How do you solve mass if you have the volume and density?
Determine the value of log 3 81 If A B n(A) 4, n(B) 7 the n(A B) = The product of the zeros of the polynomial 7 10 2 x x is A) B) C) D) If the system of equations 4x 5y 9, 8x ky 18 has infinitely many solutions then k = A) 8 B) 9 C) 10 D) 1 The discriminant of 2 5 3 0 2 x x is A) 1 B) C) 25 D) 24
What is the density of a rock which has a mass of 35 grams and a volume of 7.0 cubic centimeters?
The density of the rock is calculated by dividing the mass (35 grams) by the volume (7.0 cubic centimeters). So, the density would be 5 grams per cubic centimeter.
Convert your densities to kg or L and compare these with values with those in g or mL?
To convert densities given in g/mL to kg/L, you need to divide by 1000. For example, 1 g/mL is equal to 0.001 kg/L. When comparing densities, the numerics will remain the same between g/mL and kg/L, but the units will be different - g/mL versus kg/L.
How many moon does it goes into the earth?
Earth has about 50 times the volume of the Moon (and 81 times the mass of the Moon).
How does the Moon's size compares to earths size?
The volume of the Moon is 2% compared to the Earth. You would need 81 objects with the mass of the Moon to match the mass of the Earth.
