Answer:
34.4
Explanation:
You would divide the mg by 1000 to get the number of grams.
<h2>
Answer: atoms</h2>
Explanation:
The given formula of the compound is
The formula says
Every mole of contains moles of atoms of hydrogen.
Given that number of moles of compound is
So,the number of moles of hydrogen atoms present is
Since each mole has atoms,
moles has atoms.
Answer:
Explanation:
Hello,
In this case, by using the ideal gas equation, we first compute the moles of oxygen at the given volume, pressure and temperature:
Then, since molar mass of gaseous oxygen is 32 g/mol, we compute the contained mass in grams as shown below:
Best regards.
Ever seen a waterfall ? what do you think happens when all that water slams into the ground below ? same as when you turn a hosepipe on a flowerbed.
also, there's hydraulic cracking where water gets into cracks and freezes, splitting rocks apart.
fast moving water can carry sediment and roll rocks along the bottom. if the water slows down, it drops the rocks and heavier sediment. if it floods a field, say, then drains away, the grass will also filter smaller particles out, or the water might evaporate and leave fine sediment behind.
The correct answer is that a pure substance cannot be physically broken down into different types of atoms.
