How many grams of solute are needed to prepare 2oz of 8% iodine solutions​
dimaraw [331]

Answer:

  4.732 grams

Step-by-step explanation:

2 US fluid ounces is exactly 59.147059125 mL of volume. 8% of that volume is 4.73176473 mL.

For a solution of this type, where 1 g/100 mL is considered a 1% solution this is the number of grams of solute needed.

  About 4.732 grams of solute are needed to prepare 2 fl oz of 8% solution.

_____

We have assumed that 1 gram of solute gives you 1 gram of iodine. Depending on the exact solute used, that may or may not be the case.

The area of rectangular field is (49m2-42m+9).Find the dimensions of the field
Drupady [299]

Answer:

The dimensions are (7m-3) by (7m-3)

Step-by-step explanation:

We have the area of the rectangular field to be:

49 {m}^{2}  - 42m + 9

We need to factorize this expression.

Let us rewrite to obtain:

{(7m)}^{2}  - 2(7 \times 3)m +  {3}^{2}

We can easily see that the expression is actually a perfect square trinomial.

This gives us:

(7m - 3)^{2}

Or

(7m - 3)(7m - 3)

Answer question from picture.
Anna007 [38]

The limit (as 'x' approaches zero) of    x²/(2x+1)  is 

             0 / (0+1)  =  0 .

You get this by substituting the limit in place of 'x'.

Sometimes that doesn't work.  Sometimes it gives you
monstrosities like   0/0,   or   1/0,   or   ∞/∞ .

But it works for this one.  There's nothing wrong with  0/1  =  zero .
