Answer:
Mass of Analyte H2C2O4 = 18.18 grams
Explanation:
The balanced equation is:
The Molarity of Oxalic acid needed can be determined using:
Here M1 = Molarity of Oxalic acid
V1 = Volume of oxalic acid
M2 = Molarity of KOH and V2 = Volume of KOH
M1 = ? , V1 = 16.8 mL , M2 = 0.501 M , V2 = 13.54 mL
Put the values and solve for M2,
We are multiplying by 2 because , 1 H2C2O4 needs 2 KOH
Hence Molarity of H2C2O4 =
0.202 M
Molar mass = H2C2O4 = 2x1 +2x12 + 4x16
= 2+24+64 = 90 gram
18.18 gram
Answer:
please only post questions if you actually need it.
Explanation:
(46x8.0)+(47x7.8)+(48x73.4)+(49x5.5)+(50x5.3) = 4792.3
4792.3/100 = 47.923 this is the average atomic mass of Titanium
Answer:
The speed of the boat-A is 47.84 knots.
Explanation:
Mass of boat-A = m
Mass of boat-B = m
Kinetic energy if the boat-A = E
Kinetic energy if the boat-B = E'
Velocity of boat-A = v = ?
Velocity of boat-B = v'= 34 knots = 34 nautical miles /hour
1 knot = 1 nautical mile per hour
1 nautical mile = 6,076 feet
34 nautical miles /hour = 34 nautical miles /hour × 6,076 ft/miles = 205,564 ft/hour
Kinetic energy of boat-A is given by :
Kinetic energy of boat-A is given by :
..[1]
Kinetic energy of boat-B is given by :
..[2]
E= 2E' (given)
[1] ÷ [2]
v' = 47.84 knots
The speed of the boat-A is 47.84 knots.
The answer would be 380 !
