Answer:
B. It contains 15.0 grams of HNO₃ per 100 grams of solution.
Explanation:
- The percent of a solute in a solution is the mass of the solute (g) per 100 g of solution.
<em>So, an aqueous solution that is 15.0 percent HNO₃ by mass means that It contains 15.0 grams of HNO₃ per 100 grams of solution.</em>
Answer: It would be A and C
Explanation: I did the test and got it right. Hope this helps!
Fluorine - 18.998 u
chromium - 51.996 u
tellurium - 127.6 u
dysprosium - 162.5 u
Answer:
45K
Explanation:
Rise in temperature = Final - initial temperature.
temperature in K = Temperature in Celsius + 273
for Celsius; T2 -T1 =45°C
for kelvin; T2+273 -(T1+273) = ?
T2+273 -T1-273 =?
T2-T1 = ?
T2-T1 =45k
hence ΔT(K) = ΔT(°C) (temperature difference in Celsius is equal to temperature difference in kelvin)
