OP already did it - CONGRATS!!
here are the steps 2 get the same ans:
(NH4)2 CO3 has 2x N, 8x H, 1x C and 3x O per molecule
so its molecular mass = 2x14 + 8x1 + 1x12 + 3x16
=28+8+12+48
=96g
of that 96g, 8x1=8g is due to Hydrogen
so by ratio n proportion, 1.00g will have 1x8/96 = 1/12g = 0.083g of H
<h2>D this is a lot of hour to found but its ok thank you for sharing your question i hope this help</h2>

Answer:
Here the force is 10N and the mass is 5 kg. Dividing both sides by 5kg, we get a = 2 m/s^2.
Answer:
False
Explanation:
Compounds are chemically combined
lemonade is not
If the squeezed lemonade is made by squeezing lemons to extract the juice and mixing it with water and sugar, it would be a homogenous mixture.
If it contains a pulp than it would be heterogeneous
Answer and Explanation:
To calculate this, simply use an equality of proportions:
50 particles : 1 billion particles = <em>x</em> tons : 1.49 million tons
The value of <em>x</em> can be solved for by multiplying the ratio on the left by the value 1.49 million / 1 billion:
So, <em>x</em> = (50)(0.00149) tons = 0.0745 tons
Then, do the same thing for the larger concentration:
<em>x</em> = (200)(0.00149) tons = 0.298 tons
