Calculating for the moles of H+
1.0 L x (1.00 mole / 1 L ) = 1 mole H+
From the given balanced equation, we can use the stoichiometric ratio to solve for the moles of PbCO3:
1 mole H+ x (1 mole PbCO3 / 2 moles H+) = 0.5 moles PbCO3
Converting the moles of PbCO3 to grams using the molecular weight of PbCO3
0.5 moles PbCO3 x (267 g PbCO3 / 1 mole PbCO3) = 84.5 g PbCO3
Answer:
The rounded answer is 9.487....
Since we have the mass of the iron ingot we can get its volume by dividing the mass (4.578) by the density of iron (7874 kgm^-3) and we get that the volume is 5.8140716x10^-4 m^3. now we convert the volume from m^3 to cm^3(1m^3=1000000cm^3) and so by multiplying 5.8140716x10^-4 by <span>1000000 we get:581.4cm^3 (1 decimal place).
the volume for any cuboid is V=l x w x s we have the volume, the length and the width, so we plug in the values and solve for s
</span>
the answer is rounded to three significant figures
hope i helped
