300.0 ml of a .250 M Na3PO4 solution is combined with 400.0 ml of a 0.500 M Pb(NO3)2 solution. How many grams of solid lead phosphate will be produced by the reaction. Assume 100% yield

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles

b is the correct

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.

no statements shown

the atomic number of carbon is six, which means that a carbon atom has six protons. carbon has three naturally occurring isotopes: carbon-12, carbon-13, and carbon-14. which of these statements are true about carbon and its isotopes? select all that appl
