Answer:
83914.52 grams
Explanation:
Given that,
Weight of a man is 185 lb
We need to find his weight in grams
For this, we must know the relation between lb and grams.
We know that,
1 lb = 453.592 grams
To find the mass of man in grams, the step is :
185 lb = (453.592 × 185) grams
= 83914.52 grams
So, the mass of a man is 83914.52 grams.

Answer:
Volume of water it can hold 63000,000 cm³
Mass of water is 63000,000 g.
Explanation:
Given data:
Length of tank = 70.00 cm
Width of tank = 300.00 mm
Height of tank = 300.00 m
Volume of water it can hold = ?
Mass of water = ?
Solution:
First of all we will convert the units into same unit.
Width of tank = 300.00 mm × 1 cm / 10 mm = 30 cm
Height of tank = 300.00 m× 100 cm / 1 m = 30000 cm
Volume of water it can hold:
V = l×w×h
V = 70.00 cm × 30 cm × 30000 cm
V = 63000,000 cm³
Mass of water:
Density of water from literature = 1 g/cm³
d = m/v
1 g/cm³ = m/ 63000,000 cm³
m = 63000,000 g
Answer:
2HI + K2SO3=>2KI+H2SO3
Explanation:When aqueous hydroiodic acid and aqueous potassium sulfite are mixed the products obtained are potassium iodide and sulfurous acid.Both reactants are ionic compounds and they undergo double replacement reaction.In a double replacement reaction the parts of the ionic compounds are changed.The product is obtained by combinig cation of one compound with anion of other compound.so in above reaction sulfurous acid is obtained which is in gaseous form and potassium iodide is an ionic compound.
