Answer:
A is the answer
Explanation:
Because water freezes when it gets to a certain temperature
Answer:
3.29 M
Explanation:
Molarity refers to the molar concentration of a solution and it can be calculated using the formula below:
Molarity (M) = number of moles (n) ÷ volume (V)
According to this question, the mass of HCl was given to be 60.4 grams and the volume of water as 505 mL.
Using mole = mass/molar mass to convert mass of HCl to moles
Molar mass of HCl = 1.0079 + 35.453 = 36.4609g/mol
mole = 60.4g ÷ 36.4609g/mol
mole = 1.66mol
Volume of water = 505mL = 505/1000 = 0.505L
Molarity, M = 1.66 ÷ 0.505
Molarity of HCl solution = 3.29 M
I think it’s something like 29.95g, sorry if it’s wrong long i haven’t done this in so long
<u>Answer:</u>
<em>Actual temperature for the given temperature with thermometer with error of 6.5% is 63.8 degrees.</em>
<u>Explanation:</u>
The percentage error in thermometer is 6.5% this means that if the temperature is 100 degrees the thermometer shell show 106.5 degrees. now calculating the <em>actual temperature of the thermometer when the given temperature is 68°</em>
<em>Applying unitary method for solution 106.5</em>
Then 100 will be
= 
= <em>63.8 Degrees</em>
<em>On solving the value of this equation will give the actual temperature as 63.8 Degrees .</em>
Answer:
i think b is the answer hope this helps:))
