Answer:
The solubility of the salt is
46.75g salt/100g of H2O
Explanation:
If 7.70g of water can dissolve 3.60g at 21°C
That is 1.0g of water can dissolve (3.6÷7.7) grams of salt, that is 0.4675_g of salt at 21°C or 100 grams of water can dissolve 100×0.4675 = 46.75g
The solubility of the salt is
46.75g salt/100g of H2O
Answer:D. 9.1 mole Ar
Explanation:
364 g Ar x 1 mole Ar / 40 g Ar
= 9.1 moles Ar
Most atoms have more neutrons than protons which accounts for basically half of the nucleuses mass.
