1 answer:
Answer:
T= -99 °C.
Explanation:
Hello there!
In this case, according to the given description of the problem, it is possible for us to analyze this problem via the ideal gas equation:
However, we first calculate the moles in 3.00 grams of nitrogen gas (28.01 g/mol):
Next, we solve for the temperature as shown below:
Next, we convert the given pressure and volume to atm and L to obtain:

Answer:
It is possible she could get one.
Explanation:
To solve this problem we need to convert 98.3 kilometers/hour to miles/hour.
In other words, we <u>convert km to mi</u>, to do so we multiply 98.3 km by a <em>conversion factor</em>, putting the unit we want to have in the numerator, and the unit we want to convert in the denominator:
- 98.3 km *
= 61 mi
Given that the little old lady is doing 61 miles/hour, she could get a speeding ticket.
