Answer: UV Rays can't travel through glass, making it impossible to get a suntan because your body won't be able to respond if there is no UV getting to it.
Explanation: Glass absorbs and deflects a lot of UV light because the wavelengths aren't small enough to pass through and as a result, your body can't undergo its natural response of producing melanin, because the proteins activated by the UV damage won't be enacted.
Hey there!:
Molar mass MgCl2 = 95.2110 g/mol
So:
1 mole MgCl2 -------------- 95.2110 g
moles MgCl2 ---------------- 319 g
moles MgCl2 = 319 * 1 / 95.2110
moles MgCl2 = 319 / 95.2110
=> 3.350 moles of MgCl2
Hope that helps!
