Really need help with mass to mass,
Ridiculous trying to learn this on online schooling..

Should just post the question. Plenty of knowledgeable people here.

you should find the mass of 1 mole of the substance
h20 , it would be 2*(mass of 1 hydrogen) + mass of 1 oxygen
look up the masses in your book, given chart,or google search ,etc
the values from each source should be very very similar from each other

say the mass of 1 mole of zinc hydroxide is 19.3 grams (which is not correct)
from the balanced equation, you'd only need .5 mole of zinc if you wanted 9.65 g of zinc hydroxide

No books, charts, or google search mass calculators dont recognize half of them.

you're really behind. maybe you should go over your modules or beginning chapters.
watch a few youtube videos

I have done all of this, I have a 98% in chemistry and did 129 assignments in 2 hours. This is really hard to me, and i do it ONLINE as i stated before.
You can not go back, and you watch a video that doesn't explain anything clearly. My teacher's don't even know how to do it at my school, thats what i get for going to a Redneck school.

Vaguely recalling Chemistry ---> H = 1 proton, O = 8 protons, Zn = 30 protons. So the weights H = 1, O = 16ish, and Zn = 60ish.

So weight of.. Zn(OH)2 = 60 + 32 + 2 = 94ish.

so.. Zn in 9.6gram = 60/94 x 9.6g = 6.12g or or something close to it would be my guess... if you have the periodic table handy then you can calculate this precisely.
