A dash of vinegar and baking soda balloon system weighed 65 grams. After releasing the carbon dioxide, the system weighed 63.5 grams. How many grams of carbon dioxide were produced?

1.5 grams of carbon dioxide

Explanation:

According to this question, a dash of vinegar and baking soda balloon system weighed 65 grams. The system weighted 63.5grams after releasing the carbon dioxide in it.

This means that, to get the amount of carbon dioxide (CO2) produced in the system, we subtract the mass of the system after releasing CO2 from the initial mass of the system before releasing CO2.

That is;

Mass of CO2 produced = 65g - 63.5g

Mass of CO2 produced = 1.5grams

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
