The product is magnesium sulfate plus hydrogen gas,as per this equation:
<span>Mg + H2SO4 = MgSO4 + H<span>2(g)</span></span>
Therefore, 1 mole<span> of gold weighs </span>196.9665<span> grams. So, in 2.8 grams of gold we would have:</span>
(2.8 gram)(1 mole/196.9665<span> gram) = 0.0142 mole.</span>
From Avogadro's number, we know that there are approximately 6.02 x 1023<span>atoms/mole.</span>
Answer:
≈ 1.142 moles
Explanation:
formula is “grams given/molar mass = moles”
nitrogen’s molar mass is 14.0067g
solve:
16 / 14.0067 = 1.14231046571
or ≈ 1.142 moles
hope this helped :)
Explanation:
As the Earth rotates on its axis and revolves around the Sun, several different effects are produced. When the new moon comes between the Earth and the Sun along the ecliptic, a solar eclipse is produced. When the Earth comes between the full moon and the Sun along the ecliptic, a lunar eclipse occurs.
