Given the density of iron (Fe) is 7.87 g/cm3, determine the mass of iron (in grams) in a rectangle block with the dimensions of 12.5 in long, 3.50 in wide, and 2.50 in high. (1in = 2.54 cm).

Explanation:

Hello,

In this case, the first step is to compute the volume of the block considering the length, height and width:

Then, we compute the volume in cubic centimetres:

Finally, as the density is given by:

We solve for the mass:

Best regards.

if the concentration of products is decreased, the equilibrium will shift toward the products). add an inert gas (one that is not involved in the reaction) to the constant-volume reaction mixture: this will increase the total pressure of the system, but will have no effect on the equilibrium condition.

explanation:

they are both synthetic elements
