How many liters of water must be added to 8 liter of a 40%acid solution to obian a 10% acid solution (answer)

The equation you need to use for this kind of problems is V1 XS1 = V2 x S2 V1= 8 Lit S1 = 40%. S2 = 10% you need to calculate V2 V2= (V1x S1)/S2 =( 8 x 40)/10 = 32 Thus you need to dilute 8 lit 40% acid with water to make up the volume to 32 lit (you...

In fact, the correct sequence of the numbers is 84, 14, 12 81, 18, 9 ,88, ?, 11, If this is the case, the 2nd number = 2(first number/3rd number) thus, 84/12 x2 =14 ; 81/9 x2 =18, 88/11 x2= 16 so the answer is 16.

The equation of the line P is y= -4.5 x + 4 The equation of the line Q is y= -4.5 x + c [since it is parallel to the line P] The lile passes through the point (4, -3), Thus, -3 = -4.5X 4 +c thus, c= 4.5x 4 -3 = 18-3= 15 thus the equation of the line Q...

weight of the goid idol = 2 Kg =2000 g which has tobe replaced by the same weight of sand. 2000 g sand = Density of sand x volume of sand volume of sand = 2000/3 cm 3 = 666.6 cm3 = 0.666 lit

LxW = 24 W= 24/L 2(L+W) =22 so L+W = 11 L + 24/L =11 L2 + 24 = 11L L2 -11L + 24 =0 (L-3) (L -8) =0 So L = 3 0r 8 Thus the dimension of the rectangle is 8ft X 3ft

3.86 M K2SO4 contains 3.86 x 174.01 g K2SO4 or 671.6786 g K2SO4 per lit The volume of K2SO4 needed = 72.9/671.6786 = .1085 litre

Slope of the straight line joining two points (x1, y1) and (x2, y2) is m= (y2-y1)/ (x2-x1)= (9-1)/(-6-10) = 8/(-16) =-1/2 Thus the equation of the st. line is y = (-1/2)x + c since the line passes through (10,1), substituting in the above equation, 1...

number of oximes (answer)

Carbonyl compounds such as an Aldehyde or a ketone react with hydroxylamine (NH2OH) to form an oxime. For each carbonyl group one oxime is produced. C8H80 has one carbonyl group and is expected to form one oxime. Now we need to find out how many carbonyl compounds are possible with C8H80. Five...

The surface area of the cube is 6x2, where x is the edge Amount of paint required = thickness of the paint x surface area = 0.05 cm x 6x(30 cm)2 = 270 cm3

one number is 8 more than three times another. If the sum of the number is 16,find the number (answer)

x+3x+8 =16 4x = 8 x=2 thus the numbers are 2 and 14

let the smaller number is x then the larger is 2x Thus, x+ 2x = 39 3x =39 x= 13 Thus the numbers are 13 and 26

lateral surface area of a cylinder = diameter x 3.14 x height thus diameter = lateral surface area /3.14x height = 188.4 sq ft/ 3.14 x 10 = 188.4/31.4 ft

a building foundation has a length of 82 feet and a perimeter of 240 feet. what is the width (answer)

if w is the width, then 2(length + w)= 240 thus, length + w = 120 w = 120- length =120- 82 = 38 the width is 38 ft.
