Answer:Volume is the quantity of three-dimensional space enclosed by a closed surface, for example, the space that a substance (solid, liquid, gas, or plasma) or shape occupies or contains.
Explanation:
Answer:
The new volume, after increasing the pressure to 785 torr, will be 1.22 L
Explanation:
Step 1: Data given
Volume of neon sign is 1.51 L
Pressure of the neon gas = 635 torr
The pressure increases to 785 torr
Step 2: Calculate the volume
P1*V1 = P2*V2
⇒with P1 = the initial pressure of the gas = 635 torr
⇒with V1 = the initial volume of the gas = 1.51 L
⇒with P2 = the increased pressure = 785 torr
⇒with V2 = the new volume = TO BE DETERMINED
635 torr * 1.51 L = 785 torr * V2
V2 = (635 torr * 1.51 L ) / 785 torr
V2 = 1.22 L
The new volume, after increasing the pressure to 785 torr, will be 1.22 L
Answer:
THE FRACTION OF IODINE-125 REMAINING AFTER 360 DAYS IS 1/64.
Explanation:
half life of iodine- 125 = 60 days
Time elapsed for a decay = 360 days
using the formula:
Nt = No (1/2)^t/t1/2
The fraction left after a decay will be represented as:
Nt / No = (1/2) ^t/t1/2
Nt / No = (1/2) ^ 360 /60
Nt / No = (1/2) ^6
Nt / No = 1 / 64
The fraction of iodine-125 (Nt / No) remaining after 360 days is 1/ 64.
Answer:
Q1: c. 7.2 g.
Q2: a. 0.42 M.
Explanation:
Hello there!
In this case, according to the definition of molarity as moles of solute divided by volume of solution in liters, we can proceed as follows:
Q1: Here, given the molarity and volume we can calculate the moles of the sugar as follows:
Next, since its molar mass is about 180 g/mol, the mass turns out:
Therefore, the answer is c. 7.2 g.
Q2: Here, recalling the definition of molarity, we can just plug in the 0.629 moles and 1.500 L to obtain:
Therefore, the answer is a. 0.42 M.
Best regards!
