Solution because a solution cannot be separated by hand
<em>Mass = Moles x GFM</em>
<em>
mass = 30g so;
</em><em>30 = mol x GFM
</em>
To calculate the GFM, you require a data booklet or similar.
Mine tells me that the GFMs are:
H: 1 H₃ so 3 x 1 = 3
P: 31 P so 1 x 31= 31
O:16 O₄ so 4 x 16 = 64
GFM = 64 + 31 + 3 = 98
30 = 98 x <em>mol
</em><em>
</em><em>mol = </em>30 / 98
<em>mol = </em><u>0.31 mol</u>
The pressure of Carbon Dioxide in the bottles lower and the CO2 diffuses out from the drink.. Hence bubbles are formed.. :)
Idk it’s there’s a picture(it won’t load or no picture) but when molecules move slow and are kidna packed together it is a solid
Answer:
21
Explanation:
Formula;
Mass number = number of protons + number of neutrons
= 9 + 12
= 21
