1. Give the chemical formula for calcium phosphate.
2. A hypothetical element, Js, has three naturally occurring isotopes. The atomic mass and relative abundance of each isotope are: 35% 191 Js, 20% 185 Js,And 45% 192 Js. What atomic mass should be reported for this element?
4. Convert 200 degrees C to degrees F.
1. Assume that you have 100 g (1 g = 1%) of sample, calculate the moles for each element by dividing the mass by the molar mass (n = m/M). For C it will be 3.33 moles, H will be 6.60 moles, and O will be 3.33 moles. Next divide the number of moles for each element by the smallest value for moles, basically we are finding ...
