Answer:
345.44 g or 0.34544 kg
Explanation:
Applying
D = m/V...................... Equation 1
Where D = Density of mercury, m = mass of mercury, V = Volume of mercury.
make m the subject of the equation
m = D×V................. Equation 2
From the question,
Given: D = 13.6 g/mL = 13.6 g/cm³, V = 25.4 cm³
Substitute these values into equation 2
m = 13.6×25.4
m = 345.44 g
m = 0.34544 kg
Hence the mass of mercury is 345.44 g or 0.34544 kg
Answer:
The oxygen atom holds the electrons in a covalent bond more closely than the hydrogen atoms and develops a partial negative charge.
Explanation:
Water molecule is composed two hydrogen atoms and one oxygen atom.Both the hydrogen atom interact with the single oxygen by the formation of covalent bond.
Although the covalent bond is formed but the bonding electrons are not shared equally by both the atom.As oxygen is more electronegative than that of hydrogen atom,oxygen attract the bonding electron pair towards itself.
As a result the hydrogen atom get partial positive charge and oxygen atom gains partial negative charge.
HCl + NaOH → NaCl + H2O
No. of moles of NaOH = MV/1000
= 3.2X60/1000
= 0.192 mol
**M is your concentration of solution, V is the volume of solution either in cm³ or mL cuz they are equal**
1 mol of NaOH reacted with 1 mol of HCl. No. of moles of HCl needed to react with 0.192mol of NaOH
= 0.192x1/1
= 0.192mol
Volume of HCl = no. of moles x 1000 / M
= 0.192 x 1000 / 4.0
= 48mL
Answer:
Explanation:
Hello,
In this case given the molal solution of sucrose, we can assume there are 0.329 moles of sucrose in 1 kg of solvent, thus, computing both the mass of sucrose and solvent in grams, we obtain:
In such a way, we proceed to the calculation of the mass percent as follows:
Regards.
Answer:
if the G stands for gallons and the ml stands for milliliters then the answer would be
Explanation:
4086/5445
we can convert the gallons to ml so its easier to divide
15,467,193/5445
2,840.623140495868
which if you need to as a whole number would be 2,841
