Jordan adds 20 grams (g) of salt and 200 g of dry beans to a pot of warm water. he stirs the salt and bean into the water and then lets it sit for 15 minutes. what should jordan expect to observe after those 15 minutes?

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.

the accuracy of the data.

that's what i got you can count the number of atoms
