Answer:2kg
Explanation:
Mass =?
Acceleration = 3.0 m/s2
Force = 6.0N
Force = Mass x Acceleration
6 = Mass x 3
Mass =6/3 = 2Kg
Within the visible range of light, red<span> light waves are scattered the least by atmospheric gas molecules. So at sunrise and </span>sunset, when the sunlight travels a long path through the atmosphere to reach our eyes, the blue light has been mostly removed, leaving mostly red<span> and yellow light remaining.</span>
Answer:
![m_{NaOH}=26.7gNaOH](https://tex.z-dn.net/?f=m_%7BNaOH%7D%3D26.7gNaOH)
Explanation:
Hello,
In this case, given the molality of the solution which is 2.88 m (mol/kg) we can compute the moles of sodium hydroxide that are dissolved in the 232 grams of water (0.232 kg) as follows:
![m=\frac{n}{m_{solvent}} \\\\n=m*m_{solvent}=2.88\frac{molNaOH}{kg}*0.232kg =0.668molNaOH](https://tex.z-dn.net/?f=m%3D%5Cfrac%7Bn%7D%7Bm_%7Bsolvent%7D%7D%20%5C%5C%5C%5Cn%3Dm%2Am_%7Bsolvent%7D%3D2.88%5Cfrac%7BmolNaOH%7D%7Bkg%7D%2A0.232kg%20%3D0.668molNaOH)
Then, by using the molar mass of sodium hydroxide we compute the grams:
![m_{NaOH}=0.668molNaOH*\frac{39.998gNaOH}{1molNaOH} \\\\m_{NaOH}=26.7gNaOH](https://tex.z-dn.net/?f=m_%7BNaOH%7D%3D0.668molNaOH%2A%5Cfrac%7B39.998gNaOH%7D%7B1molNaOH%7D%20%5C%5C%5C%5Cm_%7BNaOH%7D%3D26.7gNaOH)

Answer:
• 1 kilocaloric equals 1000 gram calories
• 1 kilocalorie is equals to 4184 Joules of energy.
Explanation:
One kilocalorie is equals to 1000 gram calories because one kilo is equals to or have 1000 grams. One kilocalorie is equals to 4184 Joules of energy while on the other hand, one calorie is equals to 4.184 Joules of energy because one calorie is 1000 times smaller than Kilocalorie so calorie has also 1000 times lower energy than kilocalorie. Kilo is the prefix which means 1000 so we can say that One kilocalorie is equals to 1000 gram calories.
