75.0 mL in liters:
75.0 / 1000 => 0.075 L
1 mole -------------------- 22.4 L ( at STP)
( moles Hg) ------------- 0.075 L
moles Hg = 0.075 x 1 / 22.4
moles = 0.075 / 22.4
= 0.00334 moles of Hg
Hg => 200.59 u
1 mole Hg ----------------- 200.59 g
<span>0.00334 moles Hg ----- ( mass Hg )
</span>
mass Hg = 200.59 x 0.00334 / 1
mass Hg = 0.6699 / 1
= 0.6699 g of Hg
Answer: HOPE IT HELPS! PLS MARK AS BRAINLIEST
Explanation: The respiratory pigment, haemoglobin in red blood cells have a very high affinity of oxygen. It combines with oxygen to form oxyhaemoglobin and thus oxygen is carried from lungs to various body parts. Carbondioxide is highly soluble in water so it is mostly transported in dissolved form in our blood plasma.
Answer:
After 190 s the concentration of X will be 0.0396 M
Explanation:
Where;
Xt is the concentration of X at a time t
X₀ is the initial concentration of X
k is rate constant = 1.7×10⁻² s⁻¹
t is time = 190s
ln(Xt/X₀) = -( 1.7×10⁻²)t
ln(Xt/1.0) = -( 1.7×10⁻²)190
ln(Xt/1.0) = -3.23
Xt = 0.0396 M
Therefore, after 190 s the concentration of X will be 0.0396 M
Complete Question
A marine biologist is preparing a deep-sea submersible for a dive. The sub stores breathing air under high pressure in a spherical air tank that measures 74.0 wide. The biologist estimates she will need 2600 L of air for the dive. Calculate the pressure to which this volume of air must be compressed in order to fit into the air tank. Write your answer in atmospheres. Round your answer to significant digits.
Answer:
The pressure required is
Explanation:
Generally the volume of a sphere is mathematically denoted as
Substituting
Converting to Liters
Assume that the pressure at which the air is given to the diver is 1 atm when the air was occupying a volume of 2600L
So
From Charles law
Substituting , , , and making the subject we have
