Given the molarity of the solution is
.
The volume of the solution is 10.9/1000 L
Number of moles of HCl = Molarity * volume of the solution in L
Number of moles of HCl =*
Number of moles of HCl = 2.7 moles.
Therefore number of moles of HCl in 10.9 ml of the stomach acid is 2.7 moles
Answer:
about 3.937
Explanation:
There are exactly 2.54 cm in an inch so we have
10cm/1 * 1inch/2.54cm = 10inch/2.54 = 3.937
Answer:
Many countries are undergoing an increase in technology and standard of living.
Explanation:
24.305 g +28.08 g + 3(15.999 g)=100.382
219 g MgSIO3 (1 mole MGSIO3/100.382g)=2.181 mol MgSIO3
the answer is 2.18 mol MgSIO3
