Why is the density of an unknown metal that has a mass of 158 grams and a volume of 20 milliliters?
The density of the metal is 200 grams per 18 cubic centimeters, or 200/18 grams per cubic centimeter or 11.11 grams per cubic centimeter. We can also write our answer as 11.11 g/cc or 11.11 g/cm3 or 11.11 g-cm-3 depending on how we wish it to look. All these things say the same thing. To find the density of a material when we have a given mass and volume, we must find the mass per one unit of volume. This means dividing the volume units into the mass uints to generate that mass per one unit of volume figure. It is the mass per one unit of volume that is the density of a material.
What metal has a mass of 158g and a volume of 20mL?
To find the density of the metal, divide its mass by its volume. In this case, the density would be 7.9 g/mL. This density value can help identify the metal by comparing it to known densities of different metals.
Why could gliese 158g support life?
Gliese 158g is within the habitable zone of its star, which means it could potentially have liquid water on its surface. It also has a similar size and mass to Earth, which increases the likelihood of having a stable atmosphere. These conditions make Gliese 158g a candidate for potentially supporting life.
What is the molar mass for the following compound rounded to the nearest gram na2s2o3?
Na2S2O3 That's 2 sodiums at 23 each, 2 sulfurs at 32 each, and 3 oxygens at 16 each. 23+23+32+32+16+16+16=158g/mol.

Molar mass of 158g of ice?
The molar mass of ice is 18.015 g/mol. To find the number of moles in 158g of ice, divide the mass by the molar mass: 158g / 18.015 g/mol = 8.77 moles.

What is the mass of 2.55 mol of KMnO4?
To find the mass of 2.55 mol of KMnO4, you can use the molar mass of KMnO4, which is approximately 158.034 g/mol. Multiply the molar mass by the number of moles: 158.034 g/mol * 2.55 mol = 402.84 g. Therefore, the mass of 2.55 mol of KMnO4 is 402.84 grams.
What is the percent composition of KMnO4?
Potassium permanganate, or KMnO4, has a molar mass of 158g/mol. (39+55+16x4). % composition of K: 39/158=0.247=24.7%. % composition of Mn: 55/158=0.348=34.8%. % composition O: 64/158=0.405=40.5%.
