Well i suspect it to be water-- yes water btw the answers are 1B 2B 3D 4B 5B 100% Correct
Answer:
10kg = 10 x 1000 = 10,000g
Explanation:
To know the quantity with the largest mass, we have to express all the units in grams:
for: 2 x 10mg = 2 x 10 x 10⁻³ = 0.02g
0.001kg = 0.001 x 1000 = 1g
1 x 10⁵ng = 1 x 10⁵ x 10⁻⁹ = 0.0001g
2 x 10²cg = 2 x 10² x 10⁻² = 2g
10kg = 10 x 1000 = 10,000g
Note:
10⁻ ¹ deci(d)
10⁻² centi(c)
10⁻³ milli(m)
10⁻⁹ nano(n)
10³ kilo(k)
Covalent bonds keep the hydrogen and oxygen atoms together
Answer:
The answer to your question is molality = 0.61
Explanation:
Freezing point is the temperature at which a liquid turns into a solid if a solute is added to a solution, the freezing point changes.
Data
Kf = 1.86 °C/m
molality = ?
ΔTc = 1.13°C
Formula
ΔTc = kcm
Solve for m
m = ΔTc/kc
Substitution
m = 1.13 / 1.86
Simplification and result
m = 0.61
Answer:
none of the above is the answer
