Answer:
The molarity of a solution prepared by dissolving 54.3 g of Calcium nitrate into 355 mL of water is 0.9881M
Molarity of solution is the ratio of the number of moles of the substance to the volume.
n is the number of moles of the compound
Mass of calcium nitrate = 54.3g
Molar mass of calcium nitrate = Ca(NO₃)₂ = 164.088 g/mol
Get the required molarity;
Hence the molarity of a solution prepared by dissolving 54.3 g of Calcium nitrate into 355 mL of water is 0.9881M

Answer: uhh what?? im confused
Based on the excerpt from the contemporary composer Aulis Sallinen, the melody is played by a trombone: False.
<h3>What is an inference?</h3>
An inference refers to a process through which a reader or listener can deduce the meaning or message (information) such as melody, that's associated with an event or musical composition, especially through induction.
Based on the excerpt from the contemporary composer Aulis Sallinen, we can infer and logically deduce that the melody is played by a flute, rather than a trombone.

Answer:
3.5 K
Explanation:
When a sample of a substance releases heat energy, its temperature decreases according to the equation:
where
Q is the heat energy released
m is the mass of the substance
C is the specific heat capacity
is the initial temperature
is the final temperature
For the block of brass in this problem, we have:
m = 0.1 kg is the mass
Q = -56.4 J is the heat energy released (negative since it is released)
C = 380 J/kg K is the specific heat capacity of brass
is the initial temperature
Solving for , we find the final temperature:
