<span>Tin has a molecular weight of 118.7 That is the mass in grams of one mole. 3.50
</span><span>118.7 = 415Four hundred and fifteen grams</span>
So first find the moles of the H₂SO₄: Mass = Moles x RFM
so mass = 5.25 x 98 = 514.5g of <span>H₂SO₄</span>
so to find how many Liters of solution use:
Volume = Density x Grams of solute (per kg +1000)
density = 1.266 x 514.5 +1000 = 1917.357kg/l
now use equation: Conc. = Moles / Volume of solution to find the conc.
Conc. = 5.25 x 1917.357 = 4.39Mol⁻¹
Hope that helps
Answer:
Wind is caused by differences in air pressure.
An anemometer is a tool for measuring wind speed.
The wind-chill factor has a cooling effect
Explanation:
The first one is it increases
The second one cold water is more dense
it makes it colder
A voltaic cell operates such that the ions move from the negative electrode to the positive electrode.The negative electrode is the cathode while the positive electrode is the anode. This is in reverse to the cation-anion nomenclature. Hence, the answer to this problem is choice 2.
