<h2>Answer:</h2>
<em>Given data:</em>
1 kilogram = 1,000 grams
how many kilograms is 1,216 grams?
<em>Solution:</em>
1000 grams = 1 kilogram
1 gram = 1/1000 kilograms
1216 grams = 1/1000 * 1216 = 1.216 kilograms.
<em> Hence 1216 grams = 1.216 kilograms.</em>
Answer:
The correct answer is physical properties and/or phase properties.
Explanation:
Chemical properties can alter the substance (if you burn wood, it becomes ash and is no longer wood).
Reactive properties are also chemically changing the substance.
Phase properties are where the element can be in solid, liquid, or gas form so these could also be an answer.
Given
V1 = 35L
T1 = 20.00 C = 293.0 K
V2 = ???
T2 = 45 C = 318 C
Formula
V1/T1 = V2/T2
Sub and Solve
45/293 = x / 318 Cross multiply
45*318 = 293x Divide by 293
45*318/293 = x
14310 / 293 = x
x = 48.84
Use the grams to moles first. The molar mass of sodium is 22.99g, so 10/22.99 ≈ 0.43 moles. The use moles to atoms conversions. 0.43 x (6.022 x 10^23), which would be about 2.62 x 10^23 atoms in 10g of sodium.
