The reaction is: HCl + Na HCO3 → NaCl + H2CO3, which is already balanced.
Then the molar ratios are 1 mol HCL : 1 mol NaHCO3
You know the mass of NaHCO3 is 0.100 g, then you can find the number of moles using the molar mass of NaHCO3
molar mass of NaHCO3 is 23 g/mol + 1 g/mol + 12g/mol + 3*16g/mol = 84 g/mol
And the number of moles is: 0,100 g / 84 g/mol = 0,0012 mol of NaHCO3.
Then, from the ratio 1:1, you know that, at the titration point, the number of moles of HCl is the same: 0,0012 mol of HCl.
Now from the fomula of molarity you have: M = #of moles / V in liters
=> V in liters = # of moles / M = 0.0012 mol / 0.100 M = 0.012 liters
Answer: 0.012 liters of HCL
Answer:Today they will practice measuring different liquids. They will use a container called a graduated cylinder to measure liquids. Graduated cylinders have numbers on the side that help you determine the volume. Volume is measured in units called liters or fractions of liters called milliliters (ml).

Answer: some sort of reaction
Explanation: science
The partial pressure of nitrogen in the problem is 725 - 231 = 494 mmHg.
494 / 760 = 0.650 atm. To continue, we will use the ideal gas equation to find the mole of N2 and from that, we can find the mass of N2.
PV = nRT ----> n= PV/RT
Find the mole of Nitrogen
Given P=0.650 atm
n= (0.650)x(255/1000) / (0.082 x 338)
= (0.650) (0.255) / 27.716
= 0.16575 / 27.716
= 0.0060 moles
Find the mass of nitrogen
G= n x Mr (N2)
= 0.0060 x 28
= 0.168 grams
So the mass of nitrogen is 0.168
