I don’t know how to explain it. Sorry :(
Answer:
0.5475 grams of stomach acid, HCl, are neutralized by one tablet of Tums.
Explanation:
Mass of calcium carbonate = 750.0 mg = 0.750 g
Moles of calcium carbonate =
According to reaction , 1 mole of calcium carbonate reacts with 2 moles pf HCl.
Then 0.0075 moles of calcium carbonate will recat with:
of HCl.
Mass of 0.015 mol of HCl:
0.015 mol × 36.5 g/mol = 0.5475 g
0.5475 grams of stomach acid, HCl, are neutralized by one tablet of Tums.
Answer:
please read the answer above
Answer:
16.8 L
Explanation:
From the question given above, the following data were obtained:
Number of mole of He = 0.750 mole
Volume of He =?
Recall:
1 mole of any gas occupy 22.4 L at STP. This also implies that 1 mole of He occupies 22.4 L at STP.
Finally, we shall determine the volume occupied by 0.750 mole of He. This can be obtained as follow:
1 mole of He occupied 22.4 L at STP.
Therefore, 0.750 mole of He will occupy = 0.750 × 22.4 = 16.8 L at STP.
Thus, 0.750 mole of He is equivalent to 16.8 L
