Hello, I'm having trouble with this question:(adsbygoogle = window.adsbygoogle || []).push({});

mass of proton= (1.674*10^-27)kg

mass of neutron= (1.675*10^-27)kg

mass of 4He= (6.648*10^-27)kg

How many Kg of Hydrogen does the sun convert into Helium per year?

Now my main problem is that I don't have the rate of conversion. I know that each 4 protons (H atoms) for one Helium atom, but at what rate? I multiplied mass of one proton by 4 to get (6.696*10^-27)kg but I'm not really sure how to convert this into Kg per year since I dont have a rate.

Any help is greatly appreciated,

thanks
