Answer:
The two masses have the same numerical value, but the units are different
Explanation:
The two masses have the same numerical value, but the units are different: The molecular mass is the mass of 1 molecule while the molar mass is the mass of 6.022 \(×\) 1023 molecules.
To calculate the number of atoms of Cr, we first find the number of moles per unit of cubic centimeter of Cr. Then, use avogadros number for the number of atoms. Calculations are as follows:
1 cm^3 (7.15 g/cm^3) (1 mol / 51.996 g Cr) = 0.14 mol Cr
0.14 mol Cr ( 6.022 x 10^23 atoms Cr / 1 mol Cr ) = 8.28 x 10^22 atoms Cr
Answer:
i think the answer is letter C. From 35°c to 45°c
Explanation:
sorry if it is wrong
Metals are used in many products because of the characteristic properties that most metals have. The product that requires the high luster of metals is a mirror. Luster is used to describe something that reflect light off a surface. Metals are known to have the quality of reflecting light from its surface therefore it is a good material for the said product.
you can not answer this question without specifying the temperature and pressure of the copper
